1. What is Body Fat Percentage?

Body fat percentage is the total mass of fat divided by total body mass, multiplied by 100. It provides a more accurate assessment of health and fitness than body weight alone, as it distinguishes between fat mass and lean body mass.

2. How Does the Calculator Work?

The calculator uses the following formula for males:

\[ \text{Body Fat %} = 86.010 \times \log_{10}(\text{abdomen (in)} - \text{neck (in)}) - 70.041 \times \log_{10}(\text{height (in)}) + 36.76 \]

Where:

\( \text{abdomen} \) — Abdomen circumference in inches
\( \text{neck} \) — Neck circumference in inches
\( \text{height} \) — Height in inches

Explanation: This formula estimates body fat percentage based on circumference measurements and height, providing a convenient at-home assessment method.

3. Importance of Body Fat Measurement

Details: Monitoring body fat percentage helps assess health risks, track fitness progress, and maintain optimal body composition. High body fat percentage is associated with increased risk of various health conditions.

4. Using the Calculator

Tips: Measure abdomen at the navel level and neck just below the larynx. Ensure measurements are accurate and in inches. All values must be positive with abdomen measurement greater than neck measurement.
