LBM Calculator Formula

There are two formula you consider , according to Wikipedia

The Boer formula is:

For women: LBM = (0.252 × W) + (0.473 × H) − 48.3

For men: LBM = (0.407 × W) + (0.267 × H) − 19.2

W = body weight in kilograms

H = body height in centimeters.

Hume Formula :

For men: LBM = (0.32810 × W) + (0.33929 × H) − 29.5336
