health.lean-body-mass-Boer Calculator
Calculates lean body mass using the Boer, James, and Hume formulas from weight and height, with mean and range across formulas. Formula agreement within 2 kg indicates reliable lean mass estimation — larger discrepancies suggest atypical body proportions.
Inputs
Weight Kg
Body or object weight. For health calculators, usually in kg or lbs.
Height Cm
Vertical measurement. For health calculators, typically standing height without shoes.
Sex 1M 0F
Reference formula or conversion factor shown for context.
Results
lean body mass LBM (kg)
Body weight minus fat mass — muscle, bone, organs, and water. More useful than total weight for fitness assessments and medication dosing.
body fat (%)
The value at the specified point or condition.
ideal body weight IBW (kg, Devine)
The computed weight (gravitational force) or mass.
Boer formula: LBM(male) = 0.407W + 0.267H - 19.2
The specific form or variant of the result.
LBM application
Recommended use case or application for this configuration or result.
BF% classification (male)
Category assigned based on where the computed value falls on a defined scale. Check which standard or guideline defines these boundaries.
