The Lean Body Mass (LBM) is the total weight of your body without the body fat.

This calculator is based on the James formula.

The James formula for determining the lean body mass is defined as:
$$LBM$$ $$=$$ $$a$$ $$\times$$ $$weight$$ $$-$$ $$b$$ $$\times$$ $$(\dfrac{weight}{height})^2$$
$$LBM$$: The Lean Body Mass
$$weight$$: the weight measured in kilogram
$$height$$: The height measured in centimeter(cm)
The unit for LBM is: $$kilogram \text{ } (kg)$$
