Body Fat Percentage Calculator
Estimate body fat percentage using the US Navy tape measure method with metric or imperial neck, waist, hip, and height inputs.
சூத்திர விளக்கம்
Men: BF% = 495 / (1.0324 - 0.19077 log10(waist - neck) + 0.15456 log10(height)) - 450; Women: BF% = 495 / (1.29579 - 0.35004 log10(waist + hip - neck) + 0.22100 log10(height)) - 450The US Navy tape method estimates body fat percentage from circumference relationships. Women include hip circumference, while men use waist, neck, and height.
Step-by-Step Example
- 1Convert height, neck, waist, and hip measurements to centimeters when imperial units are selected.
- 2For men, calculate the log expression from waist minus neck and height.
- 3For women, calculate the log expression from waist plus hip minus neck and height.
- 4Apply the Navy equation and compare the result with sex-specific fitness category indicators.

அடிக்கடி கேட்கப்படும் கேள்விகள்
It is a practical field estimate, not a lab measurement. Results can vary with tape placement, posture, hydration, and body shape.
The Navy equation for women includes hip circumference because it improves the estimate across typical female fat distribution patterns.
BMI is a quick weight-height screen, while body fat percentage gives more body-composition context. Both are estimates and should be interpreted carefully.
Use a flexible tape, keep it level, and measure consistently. Waist is commonly measured around the navel or narrowest torso point depending on protocol.
