Army Body Fat Calculator
The Army Body Fat Calculator estimates body fat percentage from body measurements using a circumference-based method. It is useful for checking an approximate body-fat result when scale weight alone does not show body composition.
How the calculation works
The U.S. Army method uses different circumference measurements for men and women. The calculation uses logarithmic formulas, so the unit and measurement locations must match the calculator instructions.
Using the calculator
Enter your age, height, weight, and the required neck and waist or hip measurements. Measure consistently and enter the values in the units shown by the calculator. Then calculate the estimated body fat percentage.
Understanding the result
The result is an estimate rather than a direct measurement of body composition. Hydration, measurement technique, body shape, and other factors can affect how closely it reflects actual body fat.
