What Is the Navy Body Fat Calculator?

The Navy body fat calculator is a reliable tool that calculates body fat percentage according to the US Navy's guidelines. It provides results based on a person's height, waist and hip measurements, and gender. This method is very useful for assessing health risks and meeting military fitness standards.

How Does the U.S. Navy Body Fat Method Work?

This method uses a mathematical formula to calculate the measurements of specific body parts. The formula is different for men and women. For example:

  • For men: height, neck and waist measurements required
  • For women: height, neck, waist, and hip measurements are required.

Fat % is determined according to a formula, which helps determine whether a person is accepted or not according to the US Navy fitness guidelines.

Navy Body Fat Calculator Formula

Men's Formula:

% Body Fat = 86.010 × log10(waist - neck) - 70.041 × log10(height) + 36.76

Women's Formula:

% Body Fat = 163.205 × log10(waist + hip - neck) - 97.684 × log10(height) - 78.387

These formulas are used by the National Institutes of Health and the US Department of Defense.
