1. What is the DA 5500 Body Fat Formula?

The DA Form 5500 body fat equation is used by the U.S. Army to estimate body fat percentage for male personnel. It uses weight and abdomen circumference measurements to determine compliance with Army body composition standards.

2. How Does the Calculator Work?

The calculator uses the DA 5500 equation:

Where:

• \( Weight \) — Body weight in pounds (lbs)
• \( Abdomen \) — Abdomen circumference in inches

Explanation: The equation accounts for the relationship between abdominal fat and overall body fat percentage, which is particularly important for military fitness standards.

3. Importance of Body Fat Calculation

Details: The Army uses body fat percentage to assess physical readiness and ensure soldiers meet health and fitness standards. Exceeding maximum allowable body fat can affect career progression.

4. Using the Calculator

Tips: Measure abdomen circumference at the level of the navel while standing relaxed. Weight should be measured in the morning before eating. All values must be valid (weight > 0, abdomen > 0).

Q4: Are there limitations to this equation?
A: The equation may be less accurate for very muscular individuals or those with unusual body fat distribution.

Q5: How often should body fat be measured?
