The Body Mass Index(BMI) formula was developed by Belgium statistician Adolphe Quetelet (1796-1874), and was known as the Quetelet Index. BMI is also referred to as 'body mass indicator'. BMI is an internationally used measure of obesity.
How to calculate BMI - for users who wish to manually calculate BMI we have provided a bmi formula for both imperial & metric measurements (we also offer an online BMI Calculator).
Body mass index calculation is very straightforward. Calculating body mass index requires only two measurements: height & weight.
The imperial bmi formula accepts weight measurements in pounds & height measurements in either inches or feet.
1 foot = 12 inches
inches² = inches * inches
( lbs/inches² )
|(weight in pounds * 703 )|
|height in inches²|
The metric bmi formula accepts weight measurements in kilograms & height measurements in either cm's or meters.
1 meter = 100cms
meters² = meters * meters
( kg/m² )
|weight in kilograms|
|height in meters²|
|25 - 29.9||Overweight|
|30 & Above||Obese|
If you have calculated BMI use the table above to find your weight status. Different nations & organizations use different BMI ranges to classify weight status.
Our table is in keeping with the internationally recognized, US Department of Health & Human Services weight status categories.
