📚 Understanding Body Fat
What is Body Fat?
Body fat percentage is the proportion of fat relative to total body weight. It includes essential fat needed for normal functioning and storage fat for energy reserves.
U.S. Navy Method
This calculator uses the U.S. Navy body fat measurement method, which estimates body fat percentage based on circumference measurements of specific body parts.
Health Considerations
Body fat percentage is a better indicator of fitness than BMI alone, as it accounts for muscle mass and body composition differences between individuals.
Body Fat Formulas
The U.S. Navy method uses the following formulas:
Male Formula
BF% = 495 / (1.0324 - 0.19077 × log₁₀(waist-neck) + 0.15456 × log₁₀(height)) - 450
Female Formula
BF% = 495 / (1.29579 - 0.35004 × log₁₀(waist+hip-neck) + 0.22100 × log₁₀(height)) - 450
