Calculate lean body mass using weight and body fat percentage
Lean body mass (LBM) is the mass of the body minus the fat. It includes the weight of the bones, muscles, and organs. LBM is an important metric for athletes and individuals monitoring their fitness progress.
LBM is calculated by subtracting the body fat weight from the total body weight. The formula is straightforward: LBM = Body Weight - (Body Weight * Body Fat Percentage).
Enter your weight and body fat percentage to calculate your lean body mass. You can switch between metric and imperial units using the toggle.
| Weight | Body Fat % | LBM |
