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 body composition than weight alone and is an important indicator of health and fitness.

2. How Does the Calculator Work?

The calculator uses the body fat percentage formula for men:

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

Where:

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

Explanation: This formula uses logarithmic transformations of body measurements to estimate body fat percentage based on the relationship between body circumferences and adiposity.

3. Importance of Body Fat Measurement

Details: Monitoring body fat percentage is crucial for assessing health risks, tracking fitness progress, and developing appropriate nutrition and exercise plans. High body fat percentage is associated with increased risk of various health conditions.

4. Using the Calculator

Tips: Enter accurate measurements in inches. Measure abdomen at the level of the navel and neck just below the larynx. All values must be valid positive numbers, with abdomen measurement greater than neck measurement.
