Estimate relative fat mass from sex, height, and waist circumference.
| RFM | – |
Use this calculator for the Woolcott RFM tape estimate: 64 − 20 × (height ÷ waist) for men and 76 − 20 × (height ÷ waist) for women, with height and waist in the same unit. It is another circumference estimate, not DEXA or a Bod Pod. Measure waist at the navel.
Height and waist can be entered in centimetres (cm) or inches (in); the calculator converts both before the formula.
Sex: Sets the 64 vs 76 offset.
Height: Standing height, in cm or in.
Waist: Waist circumference in the same unit as height.
RFM: Relative fat mass estimate.
