Measuring body fat percentage is one of the most accurate ways to assess health and fitness. Unlike weight alone, which cannot differentiate between fat and lean tissue, body fat percentage gives insight into your actual body composition.
A Body Fat Percentage Calculator estimates the proportion of fat in your body based on inputs like weight, height, age, gender, and sometimes additional measurements such as waist, neck, and hip circumference. This tool is invaluable for anyone aiming to lose fat, gain muscle, or maintain a healthy balance between lean mass and fat.
