Body Fat Calculator – BMI-based Method calculator inputs, explained

Each control below is a real variable in BMI-based body-fat estimate (not DXA). If a unit is already printed, do not convert it again. The sample is a walkthrough, not a clinical target.

Sex

Sex switches the constant in Mifflin-St Jeor and similar equations. It is not a gender-identity questionnaire. The sample uses male. Overwrite it when your chart or scale does not look like the demo.

Height

Height must match the unit on the label. Mixing cm and inches is the usual way BMI and BSA go off by a factor of two. The sample uses 175 cm. Overwrite it when your chart or scale does not look like the demo.

Neck

Neck uses the unit printed on the label. Match that unit; the engine will not guess. The sample uses 38 cm. Overwrite it when your chart or scale does not look like the demo.

Waist

Waist uses the unit printed on the label. Match that unit; the engine will not guess. The sample uses 86 cm. Overwrite it when your chart or scale does not look like the demo.
