Formula

For Men:
LBM = 0.407 × weight + 0.267 × height (in cm) − 19.2

For Women:
LBM = 0.252 × weight + 0.473 × height (in cm) − 48.3

How to Use

1. Select your gender (men or women).
2. Enter your weight in kilograms.
3. Enter your height in meters.
4. Click the Calculate button to get your Lean Body Mass in kilograms.

Example

• Gender: Men
• Weight: 70 kg
• Height: 1.75 m

Using the formula for men:
LBM = 0.407 × 70 + 0.267 × (175) − 19.2 = 28.49 + 46.73 − 19.2 = 56.02 kg
