1. What is the Army Body Fat Calculator (Old Method)?

Definition: This calculator estimates body fat percentage using the U.S. Army's old formula based on neck and waist circumference measurements and height.

Purpose: It helps military personnel and civilians assess body composition according to the previous Army standards.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Waist \) — Waist circumference at navel (inches)
• \( Neck \) — Neck circumference (inches)
• \( Height \) — Total height (inches)

Explanation: The formula uses logarithmic transformations of the difference between waist and neck measurements, adjusted for height.

3. Importance of Body Fat Measurement

Details: The U.S. Army uses body fat percentage standards to ensure soldiers meet physical readiness requirements for optimal performance and health.

4. Using the Calculator

Tips:

• Measure waist at the navel while standing relaxed
• Measure neck below the larynx with tape sloping downward
• All measurements must be in inches
• Waist must be greater than neck measurement
