๐ Body Fat Calculator
Estimate body fat from neck, waist and hip measurements.
How it works
- We use the U.S. Navy circumference method with height, neck and waist (and hips for women).
- Enter height in feet and inches or centimetres. Tape measurements are in centimetres for accuracy.
- Results are estimates - useful for trends, not clinical diagnosis.
Common questions
How do I measure waist?
Measure at the widest point of your abdomen, usually near the navel, after a normal breath out. Keep the tape level and snug, not tight.
Why centimetres for neck and waist?
Tape measures marked in centimetres give finer accuracy for this formula. Convert from inches if needed (1 inch รขโฐห 2.54 cm).
