The DA Form 5500 Calculator is designed to accurately determine an individual’s body fat percentage, a critical factor in assessing physical fitness and eligibility for certain roles, especially within the military. It utilizes specific body measurements and a mathematical formula to estimate body fat, thus aiding individuals in monitoring their health and fitness levels. This calculator caters not only to military personnel but also to civilians who aim to maintain a healthy body composition.
Formula of DA Form 5500 Calculator
The calculation of body fat percentage through the DA Form 5500 Calculator involves distinct formulas for men and women, reflecting differences in body composition and distribution of fat. The formulas are as follows:
- Men: % Body Fat = (86.010 * log10(waist – neck)) – (70.041 * log10(height)) + 36.76
- Women: % Body Fat = (163.205 * log10(waist + hip – neck)) – (97.684 * log10(height)) – 78.387
These formulas are based on anthropometric measurements, where the waist, neck, and hip (for women) circumferences are measured in inches, and the individual’s height is also taken into account.
