BMI

 

Body mass index (BMI) is a measure of body fat based on your weight in relation to your height.

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

Ethnicity can also affect the risk of some health conditions. For example, adults of Asian origin may have a higher risk of health problems at BMI levels below 25.

Standard Formula:

BMI = (weight in pounds / (height in inches x height in inches)) x 703

Metric Formula:

BMI = (weight in kilograms / (height in meters x height in meters))

Measurements:

Under 18.5: Underweight

18.5 - 24.9: Healthy

25 - 29.9: Overweight

30 or greater: Obese
