How accurate is the US Navy method?

The US Navy method is reasonably accurate for most people, with an error margin of about 3-4%. It's more accurate than BMI for assessing body composition but less precise than DEXA scans or hydrostatic weighing.

Why do women need hip measurements?

Women typically store more fat in the hip and thigh areas, so hip measurement is included in the female formula to account for this difference in fat distribution patterns between men and women.
