1. What is Body Fat Percentage?

Body fat percentage is the total mass of fat divided by total body mass, multiplied by 100. It is a more accurate indicator of health 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 females:

\[ \text{Body Fat %} = 163.205 \times \log_{10}(\text{waist} + \text{hip} - \text{neck}) - 97.684 \times \log_{10}(\text{height}) - 78.387 \]

Where:

Waist - Waist circumference at the narrowest point (inches)
Hip - Hip circumference at the widest point (inches)
Neck - Neck circumference just below the larynx (inches)
Height - Total height in inches

Explanation: This formula uses logarithmic transformations of body measurements to estimate body fat percentage based on established anthropometric relationships.

3. Importance of Body Fat Measurement

Details: Monitoring body fat percentage is important for assessing health risks, tracking fitness progress, and maintaining optimal body composition. High body fat percentage is associated with increased risk of various health conditions.

4. Using the Calculator

Tips: For accurate results, measure circumference at the correct anatomical locations. Use a flexible tape measure and ensure it's level around the body. All measurements should be in inches.
