How this calculator works
The US Navy method estimates body fat from circumference measurements rather than skinfold calipers or DEXA scans. It's reasonably accurate for most body types but less reliable at the extremes (very lean athletes or very high body fat).
For a clinically precise measurement, ask about a DEXA scan or hydrostatic weighing.
