This body fat calculator is designed to measure the body fat percentage of a man or woman using the US Army standards found in AR 600-9 by using three measurements of each part of the soldier's body.

Circumference Sites and Landmarks for Males

Neck

Measure the neck circumference at a point just below the larynx (Adam’s apple) and perpendicular to the long axis of the neck. Do not place the tape measure over the Adam’s apple. Soldier will look straight ahead during measurement, with shoulders down (not hunched). The tape will be as close to horizontal as anatomically feasible (the tape line in the front of the neck will be at the same height as the tape line in the back of the neck). Care will be taken to ensure the shoulder/neck muscles (trapezius) are not involved in the measurement. Round neck measurement up to the nearest half inch and record.

Abdomen

Measure abdominal circumference against the skin at the navel (belly button) level and parallel to the floor. Arms are at the sides. Record the measurement at the end of Soldier’s normal, relaxed exhalation. Round abdominal measurement down to the nearest half inch and record.


Circumference Sites and Landmarks for Females

Neck

This procedure is the same as for males.

Waist (Abdomen)

Measure the natural waist circumference, against the skin, at the point of minimal abdominal circumference. The waist circumference is taken at the narrowest point of the abdomen, usually about halfway between the navel and the end of the sternum (breastbone). When this site is not easily observed, take several measurements at probable sites and record the smallest value. The Soldier’s arms must be at the sides. Take measurements at the end of Soldier’s normal relaxed exhalation. Tape measurements of the waist will be made directly against the skin. Round the natural waist measurement down to the nearest half inch and record.

Hip

The Soldier taking the measurement will view the person being measured from the side. Place the tape around the hips so that it passes over the greatest protrusion of the gluteal muscles (buttocks), keeping the tape in a horizontal plane (parallel to the floor). Check front to back and side to side to be sure the tape is level to the floor on all sides before the measurements are recorded. Because the Soldier will be wearing authorized physical fitness uniform trunks, the tape can be drawn snugly without compressing the underlying soft tissue to minimize the influence of the shorts on the size of the measurement. Round the hip measurement down to the nearest half inch and record.

This body fat calculator is designed specifically to follow the guidelines put forth by AR 600-9 "The Army Body Composition Program" and will calculate body fat percentage for women and for men.


How to use the Body Fat Calculator

How to calculate body fat percentage:

1. Enter either male or female in the gender field.

2. Enter the height in inches (round to the nearest half inch).

3. Enter the three measurements taken of the circumference of the neck.

4. Enter the three measurements taken from the circumference of the waist.

5. (Only for calculating body fat percentage for women) Enter the three measurements taken from the circumference of the hips.

Note: Enter All information in the orange fields when using the body fat percentage calculator.
