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:
\(LBM\): The Lean Body Mass
\(height\): \(= height_{feet} + height_{inch}\)
\(weight\): the weight measured in pound(lbs)
\(height_{feet}\): The first part of the height measured in feet. For example \({\color{rgb(230,179,255)} 5}\) in \({\color{rgb(230,179,255)} 5}\)'10''
\(height_{inch}\): The second part of the height measured in inch. For example \({\color{rgb(230,179,255)} 10}\) in 5'\({\color{rgb(230,179,255)} 10}\)''
The unit for LBM is: \(kilogram \text{ } (kg)\)
