Common limitations
The formula estimates non-fat body mass from height, weight, and sex. The result is a general estimate, not a body composition scan.
This calculator uses the selected inputs and the fixed formula behind the tool to produce an estimate. Review the units, assumptions, and result labels before using the output for planning.
Health results are screening or planning estimates only. They do not diagnose health status or replace advice from doctors, dietitians, or qualified healthcare professionals.
