A lean body mass helps you calculate lean body mass values accurately and instantly.
Calculate your lean body mass using the Boer formula for body composition analysis.
Men: LBM = (0.407 × weight_kg) + (0.267 × height_cm) − 19.2
Women: LBM = (0.252 × weight_kg) + (0.473 × height_cm) − 48.3
Fat Mass = Weight − LBM
Body Fat % = (Fat Mass / Weight) × 100
The Boer formula estimates lean body mass from height and weight. It's commonly used in clinical settings for medication dosing.
