How do you calculate a female/male Soldiers body fat percentage if her/his measurements are not on the look up tables (Figures B5 and B6) in AR 600-9?
The following formula is the DoD body fat equation mentioned in Department of Defense Instruction (DoDI) 1308.3, “DoD Physical Fitness and Body Fat (BF) Programs Procedures”., dated 5 November 2002. Just insert the Soldiers’ circumference and height (in inches). WOMEN: The equation for women is: % body fat = [163.205 x log10 (waist + hip – neck)] – [97.684 x log10 (height)] – 78.387 CIRCUMFERENCE AND HEIGHT MEASUREMENTS MUST BE IN INCHES Solve the equation using actual measurements: SAMPLE Neck = 15.0″; waist = 42″; hip = 44″; height = 64″ % body fat = [163.205 x log10 (42 +44 – 15)] – 97.684 x log10 (64)] – 78.387 A. Solve [163.205 x (log10 (71))]. Take the Log10 (71) = 1.85 (when using a calculator be careful not to use LN (natural log), rather us the LOG key so you would enter 71 and press LOG) B. Solve [97.684 x (Log10 (64))]. Take the Log10 (64) = 1.81 (when using a calculator be careful not to use LN (natural log), rather us the LOG key so you would enter 64 and press LOG) C. Sol
