Calculating lean body mass helps you get a better grasp of your body’s composition and aids in setting fitness goals, monitoring progress, and even assessing potential health risks.

### Formulas Developed by Experts

Our lean body mass calculator is built on the foundation of formulas developed by renowned researchers in the field. These formulas include the contributions of Boer, James, Hume, Peterson, and Schlüssel. Each formula takes into account different variables such as height, weight, and biological sex to provide accurate results. The formulas using by this calculator are as follows:

Boer Formula:

• For males: LBM = (0.407 * weight in kg) + (0.267 * height in cm) – 19.2
• For females: LBM = (0.252 * weight in kg) + (0.473 * height in cm) – 48.3

James Formula:

• For males: LBM = (1.1 * weight in kg) – (128 * ((weight in kg / height in cm)^2))
• For females: LBM = (1.07 * weight in kg) – (148 * ((weight in kg / height in cm)^2))

Hume Formula:

• For males: LBM = (0.32810 * weight in kg) + (0.33929 * height in cm) – 29.5336
• For females: LBM = (0.29569 * weight in kg) + (0.41813 * height in cm) – 43.2933

Peterson Formula:

• For males: LBM = (0.407 * weight in kg) + (0.267 * height in cm) – 19.2
• For females: LBM = (0.252 * weight in kg) + (0.473 * height in cm) – 48.3

Schlüssel Formula:

• For males and females: LBM = (0.251 * weight in kg) + (0.434 * height in cm) – 48.3
