Use this Navy body fat calculator to estimate body fat percentage from height, neck, waist, and hip measurements with sex-specific inputs in centimeters or inches.
Use one unit for every field. This calculator converts centimeters to inches before applying the standard Navy formula.
Measure the neck just below the larynx. Men usually measure waist at the navel. Women usually measure waist at the natural waist and hips at the widest point.
This Navy body fat calculator provides a general estimate only and is not medical advice. Do not use it alone to diagnose a condition, judge nutrition status, or make treatment decisions. For personal health guidance, speak with a qualified healthcare professional.
