The body fat percentage is the ratio between a person's total body fat and total mass (commonly known as weight).

This calculator uses the 4-site Durnin/Womersley skinfold method to help determine the body fat percentage, however the 4-site Durnin/Womersley skinfold method is known to overestimate the body fat percentage for some people.

Please measure your triceps, biceps, subscapular and suprailiac using a body fat caliper regardless of your gender.

The 4-site Durnin/Womersley formula for body density is used in combination with the Siri equation to determine the body fat percentage, which can be defined as:
$$BFP$$ $$=$$ $$\dfrac{495}{BD}$$ $$-$$ $$450$$
$$BFP$$: Body fat percentage
$$triceps$$: the skin fold measurements of the triceps
$$biceps$$: the skinfold measurement of the biceps
$$suprailiac$$: the skinfold measurement of the suprailiac
$$subscapular$$: the skinfold measurement of the subscapular
$$age$$: your age measured in years
The SI unit for BFP is: $$%$$
