This on-line RFM calculator takes your height and waist circumference and calculates the Relative Fat Mass in the body. This calculator is only for adults of age 20 and above. Just like BFP calculator, this calculator will also give an approximate result.
Relative Fat Mass (RFM) is another estimator for calculating the percentage of fat in the human body. This was put forward by Orison O. Woolcott & Richard N. Bergman in a study (Relative fat mass (RFM) as a new estimator of whole-body fat percentage ─ A cross-sectional study in American adult individuals). RFM is not as popular as Body Fat Percentage (BFP). However, accuracy of RFM is claimed to be higher than BFP for adult men and women.
There are separate formulas for men and women to calculate the Relative Fat Mass. Let's see them.
RFM for Men = 64 − (20 × (Height ÷ Waist) )
RFM for Women = 76 − (20 × (Height ÷ Waist) )
The above individual formulas for men and women can be combined like this.
RFM = 64 − (20 × (Height ÷ Waist) ) + (12 × Sex)
|Essential Fat Percent||10-13%||2-5%|
|Fat Percent for Athletes||14-20%||6-13%|
|Obese Level||32% and above||25% and above|
