BMI for Children

For the calculation of BMI for children and teenagers/adolescents, the process involves the use of age-relevant norms that allow comparison of a child‘s BMI with those of others the same age. This is so because in the case of children, there are other important factors that affect the changes of weight and height:

Different children have different fat concentrations and metabolism.

There are differences in growth rates of children with respect to age (both for height and weight) which means that the BMI ranges in different ages would vary.

The growth rates and the fat concentration of bodies is also different in the case of growing girls and boys.

Keeping all such factors in mind, the calculation of BMI for children and adolescents are calculated by taking their age and gender into consideration as well as plotting a BMI Percentile Chart which shows the percentage of children who fall into the various BMI categories on the basis of their ages . By doing this, we are not simply calculating the BMI of a child or teen by using their weight and height but also comparing it to others of their age and gender to form a nuanced idea about if their BMI is higher or lower in comparison with others.

How to calculate Body Mass Index

Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. BMI applies to most adults 18-65 years.

Who shouldn't use a BMI calculator

BMI is not used for muscle builders, long distance athletes, pregnant women, the elderly or young children. This is because BMI does not take into account whether the weight is carried as muscle or fat, just the number. Those with a higher muscle mass, such as athletes, may have a high BMI but not be at greater health risk. Those with a lower muscle mass, such as children who have not completed their growth or the elderly who may be losing some muscle mass may have a lower BMI. During pregnancy and lactation, a woman's body composition changes, so using BMI is not appropriate.

Limitations of BMI as a Measure of Health

As an indicator, the BMI is not completely void of limitations and has its own shortcomings as well.

For example, the BMI is overly simplistic in that it solely depends on two factors- weight and height, and ignores a number of other factors such as:

The muscle concentration in the body of the person

Gender, for e.g. body fat levels are normally higher for women than men. The health condition of the person, e.g. pregnancy etc. Based on a number of such factors, it can be said BMI does not give a completely accurate representation of the body fitness and fat levels in the body of a person. Another important limitation of BMI as an indicator of body fat and fitness levels is that it is based on the assumption that a lower body weight equals fitness, which may not be true as:

Some people may have other adverse body conditions which may be detrimental to body fitness despite a normal body weight.

Some people may have genetic conditions leading to a greater body weight but are otherwise completely fit and healthy.

The body fat levels may fluctuate in case of growing children and aged people.

In the case of athletes, the BMI may be high but it does not equate with an unfit body since their muscle concentration is often high.

So, the BMI may not be the best indicator of body fitness and health for a number of cases such as growing children and teenagers, older populations, athletes, pregnant women etc.

FAQ

Does normal BMI depend on age?

No for adults, the range of normal BMI is 18.5-24.9, and it does not depend on a person's age. For children, however, age is essential in assessing their weight.

What is my BMI if I am a man and weigh 75 kilos?

The answer depends on your height! Assume it is 180 cm. Then your BMI is:

BMI = weight / height²,

where the weight should be in kg and height should be in meters.

Therefore, convert height in cm to meters: 180/100 = 1.8 m.

So the BMI calculation is weight / height² = 75/1.8² = 23.148. So it is in the normal (healthy) range. Note that this result does not depend on your gender.

How to check BMI?

The BMI calculator is suitable for adults and children aged 2 years old and over. The BMI calculator may not be suitable if you think you have an eating disorder or are being treated for one. Ask a GP for advice. If you are pregnant, use your pre-pregnancy weight when calculating your BMI.

Calculator Use

The bmi calculator online finds the body mass index given weight and height. Calculate your BMI and find the BMI weight category for your height. The calculator also finds the normal weight range given your height.

Calculate BMI with weight in pounds, stones or kilograms. Enter height in inches, feet and inches, meters or centimeters.

What does BMI mean?

The body mass index or bmi online calculator is a ratio of mass to height. It is calculated as kg per square meter or pounds per square inch of height. Numeric BMI values correspond to weight categories including underweight, normal, overweight and obese.

BMI is used as an indicator of the relative healthiness of a person. The Centers for Disease Control (CDC) and the World Health Organization (WHO) recognize that people who are overweight or underweight are at higher risk for certain health conditions. BMI also enables health professionals to discuss bodyweight objectively with their patients.

BMI Formulas

Divide weight by height squared to find bmi Chemistry calculator online. Note that you need to use kg and meters the standard units for the BMI formula are kg and meters. If you need other units of measure the calculator will convert among units for you.

In metric units, using kg and meters:

[Math Processing Error]

BMI = weight ÷ height2

In metric units: BMI = weight (kg) ÷ height2 (meters)

In US units: BMI = weight (lb) ÷ height2 (inches) * 703

See additional bmi online calculator formulas below for accurate calculations in metric or imperial units.

How to Calculate bmi online calculator

Using metric units, where weight is in kilograms and height is in meters, divide weight by meters squared.

In US units, where weight is in pounds and height is in inches, divide weight by inches squared. Then multiply this figure by 703.

Example: Calculate BMI in metric units

Matilda weighs 64 kg and is 1.9 meters tall. What is her BMI?

Divide 64 by 1.92

BMI = w ÷ h2

BMI = 64 ÷ 1.92

BMI = 64 ÷ 3.61

BMI = 17.7

Normal Weight Range

Normal weight BMI is 18.5 to 24.9. To calculate your normal weight range use the following:

Metric units:

minimum weight (kg) = 18.5 × height2 (m)

maximum weight (kg) = 24.9 × height2 (m)

US units:

minimum weight (lb) = (18.5 ÷ 703) × height2 (in)

maximum weight (lb) = (24.9 ÷ 703) × height2 (in)

Body Mass Index bmi calculator online

Body mass index, or BMI, is one way to look at whether a person is at a healthy weight. BMI is a number based on height and weight. It can be used to place a person in categories ranging from underweight to obese.

But BMI doesn’t work well for everybody. There are other things to think about when deciding how much someone should weigh. If you have a BMI outside the normal range, your health care provider might also look at skinfold thickness (a measure of body fat), waist size, evaluations of your diet and family health problems, blood sugar levels, and other factors to find out if your weight might pose a health risk. To learn more about BMI and how extra body weight can affect your risk of cancer, see Body Weight and Cancer Risk.

Children's BMI

For children and young people aged between 2 to 18 years old, the BMI calculator takes into account age and gender as well as height and weight.

A child's BMI is given as a "centile". The centile number shows how their BMI compares with other children of the same age and sex as a percentage.

For example, a girl on the 75th centile is heavier than 75 out of 100 other girls her age.

The BMI calculator works out if a child or young person is:

underweight – on the 2nd centile or below

a healthy weight – between the 2nd and 91st centiles

overweight – 91st centile or above

very overweight – 98th centile or above

See a GP if you're concerned about your child's weight. They may be able to refer you to your local healthy lifestyle programme for children, young people and families.

Limitations of the BMI

If you are pregnant, use your pre-pregnancy weight when calculating your BMI.

Summary

bmi online calculator is a calculation used to estimate your body fat. Based on the bmi calculator online score, you may be categorized as being underweight, of normal weight, overweight, or having obesity. The BMI score may also be used to estimate your risk of certain diseases, like heart disease.

BMI has a number of limitations. It does not take into account your age, race, sex, fitness level, or muscle mass. As such, the same bmi online calculator can mean very different things in different people.

Multiple factors need to be considered when determining what a "healthy" body weight is. BMI is only one value of many and one that cannot be used on its own to diagnose any disease.

What is BMI?                                   

Body mass index, or BMI, gives an indication of your body size.

BMI is calculated using your weight and height (your weight divided by your height squared). Along with several other factors, like your blood pressure and cholesterol, BMI can help estimate your risk of a heart attack or stroke.

It’s important to remember that bmi online calculator is not the most reliable measure of whether your weight is in a healthy range for your height. It’s not a good overall indicator of how healthy you are, and doesn’t take into account important factors like age, gender and body composition (fat, muscle and bone).

For the following groups of people, BMI is not an accurate measure:

Some ethnic groups including Aboriginal and/or Torres Strait Islander Peoples, and people of Asian/South Asian descent.

Women who are pregnant.

People 19 years of age or younger.

Athletes or people who have a lot of muscle.

People with a condition that affects the amount of fluid in their body (for example, heart failure).

Waist measurement (waist circumference) is also important to consider alongside your bmi online calculator. Waist measurement can help to assess risk by measuring the amount of fat carried around your middle. It has some limitations though. For example, it is not accurate in women who are pregnant, children, and people with an enlarged tummy due to a medical condition.

Who can use the calculator

The BMI Physics calculator is suitable for adults and children aged 2 years old and over.

The BMI calculator may not be suitable if you think you have an eating disorder or are being treated for one. Ask a GP for advice.

If you are pregnant, use your pre-pregnancy weight when calculating your BMI.

BMI weight ranges

Adults

A BMI calculation in the Health & Wellness range is between 18.5 to 24.9.

For Black, Asian and some other minority ethnic groups, the healthy weight range is 18.5 to 23.

For people of White heritage, a BMI:

below 18.5 is underweight

between 18.5 and 24.9 is healthy

between 25 and 29.9 is overweight

of 30 or over is obese

Black, Asian and some other minority ethnic groups have a higher risk of developing some long-term conditions such as type 2 diabetes with a lower BMI. People from these groups with a BMI of:

23 or more are at increased risk (overweight)

27.5 or more are at high risk (obese)

Healthy weight

Overweight

If you want to lose weight, you can find more information at NHS Better Health.

Obese

Who shouldn't use a BMI calculator

BMI is not used for muscle builders, long distance athletes, pregnant women, the elderly or young children. This is because BMI does not take into account whether the weight is carried as muscle or fat, just the number. Those with a higher muscle mass, such as athletes, may have a high BMI but not be at greater health risk. Those with a lower muscle mass, such as children who have not completed their growth or the elderly who may be losing some muscle mass may have a lower BMI. During pregnancy and lactation, a woman's body composition changes, so using BMI is not appropriate.

Limitations of bmi online calculator

bmi calculator online does not provide information about body composition and therefore does not apply to pregnant women, children, some ethnic groups, or those with an athletic build. Age will also influence readings.

BMI for Children

For the calculation of Finance for children and teenagers/adolescents, the process involves the use of age-relevant norms that allow comparison of a child‘s BMI with those of others the same age. This is so because in the case of children, there are other important factors that affect the changes of weight and height:

Different children have different fat concentrations and metabolism.

There are differences in growth rates of children with respect to age (both for height and weight) which means that the BMI ranges in different ages would vary.

The growth rates and the fat concentration of bodies is also different in the case of growing girls and boys.

Keeping all such factors in mind, the calculation of BMI for children and adolescents are calculated by taking their age and gender into consideration as well as plotting a BMI Percentile Chart which shows the percentage of children who fall into the various BMI categories on the basis of their ages . By doing this, we are not simply calculating the BMI of a child or teen by using their weight and height but also comparing it to others of their age and gender to form a nuanced idea about if their BMI is higher or lower in comparison with others.

How to calculate Body Mass Index

Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. BMI applies to most adults 18-65 years.

Who shouldn't use a BMI calculator

BMI is not used for muscle builders, long distance athletes, pregnant women, the elderly or young children. This is because BMI does not take into account whether the weight is carried as muscle or fat, just the number. Those with a higher muscle mass, such as athletes, may have a high BMI but not be at greater health risk. Those with a lower muscle mass, such as children who have not completed their growth or the elderly who may be losing some muscle mass may have a lower BMI. During pregnancy and lactation, a woman's body composition changes, so using BMI is not appropriate.

Limitations of BMI as a Measure of Health

As an indicator, the BMI is not completely void of limitations and has its own shortcomings as well.

For example, the BMI is overly simplistic in that it solely depends on two factors- weight and height, and ignores a number of other factors such as:

The muscle concentration in the body of the person

Gender, for e.g. body fat levels are normally higher for women than men. The health condition of the person, e.g. pregnancy etc. Based on a number of such factors, it can be said BMI does not give a completely accurate representation of the body fitness and fat levels in the body of a person. Another important limitation of BMI as an indicator of body fat and fitness levels is that it is based on the assumption that a lower body weight equals fitness, which may not be true as:

Some people may have other adverse body conditions which may be detrimental to body fitness despite a normal body weight.

Some people may have genetic conditions leading to a greater body weight but are otherwise completely fit and healthy.

The body fat levels may fluctuate in case of growing children and aged people.

In the case of athletes, the BMI may be high but it does not equate with an unfit body since their muscle concentration is often high.

So, the BMI may not be the best indicator of body fitness and health for a number of cases such as growing children and teenagers, older populations, athletes, pregnant women etc.

Divide weight by height squared to find bmi calculator online. Note that you need to use kg and meters the standard units for the bmi calculator online formula are kg and meters. If you need other units of measure the calculator will convert among units for you.

In metric units, using kg and meters:

[Math Processing Error]

BMI = weight ÷ height2

In metric units: BMI = weight (kg) ÷ height2 (meters)

In US units: BMI = weight (lb) ÷ height2 (inches) * 703

See additional bmi online calculator formulas below for accurate calculations in metric or imperial units.

How to Calculate bmi online calculator

Using metric units, where weight is in kilograms and height is in meters, divide weight by meters squared.

In US units, where weight is in pounds and height is in inches, divide weight by inches squared. Then multiply this figure by 703.

Example: Calculate BMI in metric units

Matilda weighs 64 kg and is 1.9 meters tall. What is her BMI?

Divide 64 by 1.92

BMI = w ÷ h2

BMI = 64 ÷ 1.92

BMI = 64 ÷ 3.61

BMI = 17.7

Normal Weight Range

Normal weight BMI is 18.5 to 24.9. To calculate your normal weight range use the following:

Metric units:

minimum weight (kg) = 18.5 × height2 (m)

maximum weight (kg) = 24.9 × height2 (m)

US units:

minimum weight (lb) = (18.5 ÷ 703) × height2 (in)

maximum weight (lb) = (24.9 ÷ 703) × height2 (in)

Body Mass Index bmi calculator online

Body mass index, or BMI, is one way to look at whether a person is at a healthy weight. BMI is a number based on height and weight. It can be used to place a person in categories ranging from underweight to obese.

But BMI doesn’t work well for everybody. There are other things to think about when deciding how much someone should weigh. If you have a BMI outside the normal range, your health care provider might also look at skinfold thickness (a measure of body fat), waist size, evaluations of your diet and family health problems, blood sugar levels, and other factors to find out if your weight might pose a health risk. To learn more about BMI and how extra body weight can affect your risk of cancer, see Body Weight and Cancer Risk.

Children's BMI

For children and young people aged between 2 to 18 years old, the BMI calculator takes into account age and gender as well as height and weight.

A child's BMI is given as a "centile". The centile number shows how their BMI compares with other children of the same age and sex as a percentage.

For example, a girl on the 75th centile is heavier than 75 out of 100 other girls her age.

The bmi online calculator works out if a child or young person is:

underweight – on the 2nd centile or below

a healthy weight – between the 2nd and 91st centiles

overweight – 91st centile or above

very overweight – 98th centile or above

See a GP if you're concerned about your child's weight. They may be able to refer you to your local healthy lifestyle programme for children, young people and families.

What is BMI?

Body mass index, or BMI, gives an indication of your body size.

BMI is calculated using your weight and height (your weight divided by your height squared). Along with several other factors, like your blood pressure and cholesterol, BMI can help estimate your risk of a heart attack or stroke.

It’s important to remember that bmi calculator online is not the most reliable measure of whether your weight is in a healthy range for your height. It’s not a good overall indicator of how healthy you are, and doesn’t take into account important factors like age, gender and body composition (fat, muscle and bone).

For the following groups of people, BMI is not an accurate measure:

Some ethnic groups including Aboriginal and/or Torres Strait Islander Peoples, and people of Asian/South Asian descent.

Women who are pregnant.

People 19 years of age or younger.

Athletes or people who have a lot of muscle.

People with a condition that affects the amount of fluid in their body (for example, heart failure).

Waist measurement (waist circumference) is also important to consider alongside your bmi online calculator. Waist measurement can help to assess risk by measuring the amount of fat carried around your middle. It has some limitations though. For example, it is not accurate in women who are pregnant, children, and people with an enlarged tummy due to a medical condition.

Who can use the calculator

The BMI calculator is suitable for adults and children aged 2 years old and over.

The BMI calculator may not be suitable if you think you have an eating disorder or are being treated for one. Ask a GP for advice.

For people of White heritage, a BMI:

below 18.5 is underweight

between 18.5 and 24.9 is healthy

between 25 and 29.9 is overweight

of 30 or over is obese

Black, Asian and some other minority ethnic groups have a higher risk of developing some long-term conditions such as type 2 diabetes with a lower BMI. People from these groups with a BMI of:

23 or more are at increased risk (overweight)

27.5 or more are at high risk (obese)

Who shouldn't use a BMI calculator

BMI is not used for muscle builders, long distance athletes, pregnant women, the elderly or young children. This is because BMI does not take into account whether the weight is carried as muscle or fat, just the number. Those with a higher muscle mass, such as athletes, may have a high bmi calculator online but not be at greater health risk. Those with a lower muscle mass, such as children who have not completed their growth or the elderly who may be losing some muscle mass may have a lower BMI. During pregnancy and lactation, a woman's body composition changes, so using BMI is not appropriate.

Limitations of BMI

BMI does not provide information about body composition and therefore does not apply to pregnant women, children, some ethnic groups, or those with an athletic build. Age will also influence readings.

Waist measurement (waist circumference) is also important to consider alongside your bmi online calculator. Waist measurement can help to assess risk by measuring the amount of fat carried around your middle. It has some limitations though. For example, it is not accurate in women who are pregnant, children, and people with an enlarged tummy due to a medical condition.

How to calculate Body Mass Index

Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared.

A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. BMI applies to most adults 18-65 years.

Who can use the calculator

The BMI calculator is suitable for adults and children aged 2 years old and over.

The BMI calculator may not be suitable Chemistry if you think you have an eating disorder or are being treated for one. Ask a GP for advice.

If you are pregnant, use your pre-pregnancy weight when calculating your BMI.

BMI weight ranges

Adults

A BMI calculation in the Health & Wellness range is between 18.5 to 24.9.

For Black, Asian and some other minority ethnic groups, the healthy weight range is 18.5 to 23.

For people of White heritage, a BMI:

below 18.5 is underweight

between 18.5 and 24.9 is healthy

between 25 and 29.9 is overweight

of 30 or over is obese

Black, Asian and some other minority ethnic groups have a higher risk of developing some long-term conditions such as type 2 diabetes with a lower BMI. People from these groups with a BMI of:

23 or more are at increased risk (overweight)

27.5 or more are at high risk (obese)

Who shouldn't use a BMI Chemistry calculator

BMI is not used for muscle builders, long distance athletes, pregnant women, the elderly or young children. This is because BMI does not take into account whether the weight is carried as muscle or fat, just the number. Those with a higher muscle mass, such as athletes, may have a high BMI but not be at greater health risk. Those with a lower muscle mass, such as children who have not completed their growth or the elderly who may be losing some muscle mass may have a lower BMI. During pregnancy and lactation, a woman's body composition changes, so using BMI is not appropriate.

Limitations of BMI

BMI does not provide information about body composition and therefore does not apply to pregnant women, children, some ethnic groups, or those with an athletic build. Age will also influence readings.
