Lean Body Mass Calculator determines what is the weight of yours would be if you would not have any fat.

Of course, having no fat at all is not possible. In fact, if you would not have any fat, you would probably die. So **Lean Body Mass Calculator** basically needed to measure approximate numbers of ideal body fat.

The formula for lean body mass that uses James method 1,2 is:

Lean Body Weight (men) = (1.10 x Weight(kg)) – 128 x ( Weight2/(100 x Height(m))2)

Lean Body Weight (women) = (1.07 x Weight(kg)) – 148 x ( Weight2/(100 x Height(m))2)

An alternate formula for lean body mass using the method of Hume3 is

For men over the age of 16: lean body mass in kilograms = (0.32810 * (body weight in kilograms)) + (0.33929 * (height in centimeters)) – 29.5336

For women over the age of 30: lean body mass in kilograms = (0.29569 * (body weight in kilograms)) + (0.41813 * (height in centimeters)) – 43.2933
