How It Works
In inches: male BF%=86.010 log10(abdomen−neck)−70.041 log10(height)+36.76.
Female BF%=163.205 log10(waist+hips−neck)−97.684 log10(height)−78.387. Use the measurement sites specified in the reference.
Scope and Limitations
- Adult circumference estimate, not a body-composition measurement or current Army compliance determination. The model rejects impossible circumference differences and estimates outside 0–70%.
