Lean Body Mass Calculator
Estimate lean body mass with the Boer formula (an estimate, not a body-composition measurement).
Lean body mass here is an estimate from the Boer formula (1984), which uses only weight, height and sex. It is not a measurement: body-composition scans (DEXA, bioimpedance) can differ noticeably. LBM = total weight minus fat mass, and includes muscle, bone, organs and water. The fat mass and fat percentage shown are what is left after the estimate, so treat them as rough.
