1. What is the Army Body Fat Calculator?

Definition: This calculator estimates body fat percentage using the U.S. military's formula based on circumference measurements.

Purpose: It helps military personnel and civilians determine if they meet body composition standards.

2. How Does the Calculator Work?

The calculator uses the military's body fat formula:

\[ \text{Males: } 86.010 \times \log_{10}(\text{waist} - \text{neck}) - 70.041 \times \log_{10}(\text{height}) + 36.76 \] \[ \text{Females: } 163.205 \times \log_{10}(\text{waist} + \text{hip} - \text{neck}) - 97.684 \times \log_{10}(\text{height}) - 78.387 \]

Explanation: The formulas use logarithmic transformations of circumference measurements to estimate body fat percentage.

3. Importance of Body Fat Measurement

Details: The U.S. military uses body fat standards to ensure personnel meet fitness and health requirements for service.

4. Using the Calculator

Tips:

Measurements should be taken with a tape measure
Neck: Measure at the narrowest point
Waist: Measure at the navel for males, narrowest point for females
Hip: Females only - measure at the widest point
