Two persons of same height and weight may have same Body Mass Index (BMI) but different body composition. This is because of the difference in the amount and distribution of fat they have in their body. It is important to have a healthy amount of body fat to regulate body temperature, protect organs and stay energetic. But having more than the required percentage of body fat leads to serious health problems like obesity, diabetes, high blood pressure and many heart diseases. If you want to feel fit and look fit make sure you have less body fat and more muscle mass.
This calculator uses Hodgdon-Beckett formula, which is used by U.S. Navy, to calculate body fat percentage using tape measurements.
