This calculator uses the US Navy method to estimate body fat percentage. This method is based on the principle that body fat affects the relationship between body circumferences and height.

How to Measure:

• Neck: Measure around the neck, just below the larynx (Adam's apple)
• Waist (Men): Measure around the waist at the navel level
• Waist (Women): Measure around the narrowest part of the waist
• Hips (Women only): Measure around the widest part of the hips

Note: This is an estimation method. For the most accurate body composition analysis, consider DEXA scans or other professional measurement techniques.
