Military Body Fat Calculator for Calculating Your Body Fat Percentage

Military Body Fat Calculator Sign

This navy/army body fat calculator will help you to calculate your body fat percentage using only a tape measure.

The calculator's calculations are based on the Circumference Method, developed by the military (U.S. Navy and U.S. Army) for estimating the percent of body fat.

In addition to the features common to most other online body fat calculators, this one also includes standard and metric options, images showing where to take tape measurements for both males and females, built-in calculators that do all of the averaging and converting for you, and a dynamic pie chart that graphically compares your fat weight to lean body weight.

While a skin fold test (3-Site or 7-Site) is considered to be the most accurate, this calculator will help you to get a close estimate without having to go out and buy a caliper.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
