The body fat calculator works out how much body fat you have and lets you know if it is in the healthy range for your age, gender and height.
The measurements need to be accurate to within 0.5cm or 0.25 inches (centimeters tends to produce the most accurate results) and should be taken as follows:
- Height: taken without shoes
- Neck: taken below the larynx sloping slightly downward at the front
- Waist: for men at navel height, for women at the smallest point
- Hips: (women only) at the largest point
