This Lean Body Mass Calculator allows you to estimate your lean body mass (LBM) based on your gender, body weight and height. The calculator employs four powerful algorithms – the Boer, the James, the Hume, and the Peters equations – to calculate your LBM.
This tool is exceptionally easy to use. Simply follow the five basic steps below:
- 1. Select your measurement system (imperial or metric)
- 2. Select your gender (female or male)
- 3. Input details of your weight and height
- 4. Choose which equation you would like to use to calculate your LBM, and
- 5. Hit "Calculate" to compute your LBM.
Reference
Lean Body Mass (LBM) equals a person's total body weight minus their total fat mass, so the main equation is as follows:
LBM = BW - BF
Where, LBM is the lean body mass, BW is the body weight,
BF is the body fat.
Formulas
The equations to compute your LBM are listed below:
The Boer equation
Women: 0.252 × weight[kg] + 0.473 × height[cm] - 48.3
Men: 0.407 × weight[kg] + 0.267 × height[cm] - 19.2
The James equation
Women: 1.07 × weight[kg] - 148 × ( weight[kg] / height[cm] )
2
Men: 1.1 × weight[kg] - 128 × ( weight[kg] / height[cm] )
2
The Hume equation
Women: 0.29569 × weight[kg] + 0.41813 × height[cm] -
43.2933
Men: 0.32810 × weight[kg] + 0.33929 × height[cm] - 29.5336
The Peters equation
This equation is used to estimate LBM of children (up to 13 to 14 years old).
0.0817 × ( (weight[kg]) 0.6469 × (height[cm]) 0.7236 )
