About the Method:
This calculator uses the U.S. Navy body fat calculation formula, which is based on circumference measurements.
Results are estimates only and may vary from other methods such as DEXA scans or hydrostatic weighing.
For best results, take measurements in the morning before eating, using a flexible measuring tape.
