How this calculation works
The body fat calculator uses circumference measurements and the US Navy method to estimate body fat percentage. Tape measurements are convenient for trend tracking, but the result varies with measurement technique and does not replace clinical testing such as DEXA or a medically appropriate assessment.
Mathematical formula and logic
The US Navy method uses logarithmic relationships between height and circumference measurements.
Worked example
Enter consistent tape measurements taken at the same time of day to compare changes over time.
Calculation assumptions
- Measurements are entered in centimeters and converted for the formula.
- The US Navy equation is an estimate and has individual error.
- Female calculations use hip circumference; male calculations do not.
- Use consistent measurement technique when tracking trends.
