Method, example and limitations
How the calculation works
The selected circumference-based method estimates body fat from body measurements and height. Use the measurement locations and units specified on the form.
Example to check
If an estimate is 20% at a body weight of 80 kg, that corresponds to about 16 kg of fat mass; it does not mean that 20 kg is fat.
