Estimate body fat from tape measurements using a circumference equation. The result is an approximation from body measurements, not a scan or a clinical diagnosis, and does not determine eligibility under current military standards.
How to use this tool
- Select the formula option and enter height, neck and waist measurements in the displayed units.
- For the female equation also enter hip circumference.
- Repeat uncertain measurements before interpreting the estimate.
How to interpret the result
Small measurement differences can materially change the result. The calculation uses a legacy circumference-based equation and cannot account for every body shape or population. It is not interchangeable with a measured body composition assessment.
Frequently asked questions
Is this a current Navy pass/fail test?
No. The tool is an educational estimate and does not apply current service assessment procedures or acceptance rules.
