Formula

The US Army uses separate formulas for men and women to calculate the percentage of body fat.

Men

Body Fat % = [86.010 x Log₁₀(waist – neck)] – [70.041 x Log₁₀(height)] + 36.76

Women

Body Fat % = [163.205 x Log₁₀(waist + hip – neck)] – [97.684 x Log₁₀(height)] – 78.387

Where:

• waist = Waist Circumference in inches.
• hip = Hip Circumference in inches.
• neck = Neck Circumference in inches.
• height = Height in inches.
