What is FFMI?

This FFMI calculator is dedicated to estimating Fat-Free Mass Index of your body. This method is more precise in comparison to the BMI (Body Mass Index) and overcomes its shortcomings when dealing with people who are well trained, as well as professional sportsmen. In the article below you can find an explanation of what is FFMI, the comparison of BMI vs FFMI, and the FFMI scale which allows you to classify your results.
For example, If someone has 19% body fat with 65 kg weight and 160.02 cm height then his ffmi value=21 kg/m2.
He has 53 kg fat free body weight.
