Lean Body Mass Equation: Male

Lean Body Mass (Boer formula)

Lean Body Mass (kg) = (0.407 * wtKg) + (0.267 * htCm) - 19.2

Lean Body Mass (Hume formula)

Lean Body Mass (kg) = (0.32810 * wtKg) + (0.33929 * htCm) - 29.5336

Lean Body Mass (James formula)

Lean Body Mass (kg) = (1.1 * wtKg) - 128 * (wtKg/htCm)^2

Lean Body Mass Equation: Female

Lean Body Mass (Boer formula)

Lean Body Mass (kg) = (0.252 * wtKg) + (0.473 * htCm) - 48.3

Lean Body Mass (Hume formula)

Lean Body Mass (kg) = (0.29569 * wtKg) + (0.41813 * htCm) - 43.2933

Lean Body Mass (James formula)

Lean Body Mass (kg) = (1.07 * wtKg) - 148 * (wtKg/htCm)^2

Lean Body Mass Equation: Children

Lean Body Mass Peters Formula (for children up to 14 years old)

Lean Body Mass (kg) = 3.8*[0.0215*(Weight in Kg^0.6469)*(Height in cm^0.7236)]
