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 Jackson-Pollock skinfold method to help determine the body fat percentage.

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

The 4-site Jackson-Pollock formula for body fat percentage is defined as:
$$BFP$$ $$=$$ $$a$$ $$+$$ $$(b$$ $$\times$$ $$S)$$ $$+$$ $$(c$$ $$\times$$ $$S^2)$$ $$-$$ $$(d$$ $$\times$$ $$age)$$
$$BFP$$: Body fat percentage
$$triceps$$: the skin fold measurements of the triceps
$$thigh$$: the skinfold measurement of the thigh
$$suprailiac$$: the skinfold measurement of the suprailiac
$$abdominal$$: the skinfold measurement of the abdominal
$$age$$: your age measured in years
The SI unit for BFP is: $$%$$
