Body Fat Calculator
There are a number of alternative formulae that relate BMI to body fat. The method below includes ethnicity and is from a recent paper by Gallagher et al. But remember, although these calculations are based on equations published in peer reviewed journals they are only an estimate and there will be variations around the results.
The body mass index is calculated from an individual's weight divided by the square of the height. The U.S. National Heart, Lung and Blood Institute uses the body mass index to classify obesity.
To calculate your BMI and body fat fill in the table below.
The BMI values correspond to the following body analysis:
