How accurate is the Navy body fat formula?

What is the Navy method for body fat?
The U.S. Navy method calculates body fat using height and circumference measurements. For men, it uses neck and waist measurements. For women, it adds hip measurements. The formula was developed by the U.S. Naval Health Research Center.
Why is body fat percentage better than BMI?
Body fat percentage directly measures fat versus lean mass, while BMI only considers height and weight. Athletes may have high BMI but low body fat due to muscle mass. Body fat percentage provides a more accurate picture of health and fitness.
How do I take accurate body measurements?
For accurate measurements: use a flexible tape measure, measure directly on skin (not over clothing), keep the tape snug but not tight, and measure at the same time of day. For waist, measure at the narrowest point. For hips, measure at the widest point. For neck, measure just below the larynx.
