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 Navy Tape Measure Method to help determine the body fat percentage.
Please measure your height, neck, waist and hips if you are a woman. If you are a man, please measure your height, neck and abdomen.
The formula for determining the body fat percentage for an adult is defined as:
\(BFP\): Body fat percentage
\(height\): \(= height_{feet} + height_{inch}\)
\(neck\): the circumference of you neck
\(abdomen\): the circumference of you abdomen
\(height_{feet}\): The first part of the height measured in feet. For example \({\color{rgb(230,179,255)} 5}\) in \({\color{rgb(230,179,255)} 5}\)'10''
\(height_{inch}\): The second part of the height measured in inch. For example \({\color{rgb(230,179,255)} 10}\) in 5'\({\color{rgb(230,179,255)} 10}\)''
\(age\): your age measured in years
The SI unit for BFP is: \(%\)
