FFMI CALCULATOR Features

Calculates Total Body Fat

In the FFMI Calculator, the first step is entering the body fat percentage, which calculates the user’s fat from the total body weight. This app shows users how much body weight is actually muscle, bone, and other lean tissue. It also helps users to understand whether the body weight gain is from muscles or fat. For example, if the person has 80 kg and the body fat is 20%, and the fat weight is 16 kg, that means the person has a lean body mass of 64 kg. That means this is what  FFMI has access to: the muscle quality. The FFMI Calculator gives clarity by showing what kind of mass a person is gaining.

Easy to use

The FFMI Calculator is easy to use for the users because of its simplicity. There are no complex spreadsheets; it provides an online tool with a clear and user-friendly interface, and also saves users time and does not require any math skills.

The FFMI Calculator will give the result or values, with no need for a fitness expert or gym membership. Values have been given in different forms, users can be comfortable or prefer by themselves, such as centimetres, kilograms, feet and inches, and pounds.

Adjusted FFMI for Height

The FFMI Calculator can provide the adjusted FFMI of the users. It is most important when comparing users of different heights. Adjusted FFMI is important for athletes who require weight-class analysis, such as those in wrestling, boxing, or MMA. Also, Coaches and athletes use the adjusted FFMI data for strength training and diet planning. For example, a taller person has naturally more muscle compared to a shorter person, but without adjusted data, it can be misleading.

Works in Feet/inches and Kilograms

The FFMI Calculator supports multiple measurement units for the users they easily use with their own preferences. There are some units like centimetres, feet and inches, kilograms and pounds. These are the main units that are mainly used by the users. The  FFMI Calculator is highly recommended for users across different countries. For example, if someone is Indian, they use kilograms and centimetres for the check values, or if someone is U.S, they use feet and inches or pounds for their values. It’s made easier for the coaches to train with their international clients.
