The BMI Formula

Metric Units: weight (kg) / [height (m)]2

Imperial Units: 703 × weight (lbs) / [height (in)]2

The Body Mass Index (BMI) is a simple numerical value of a person’s weight in relation to their height.

BMI or RFM?

While BMI is the global standard, Relative Fat Mass (RFM) is gaining popularity because it uses height and waist circumference, often providing a more accurate estimate of body fat percentage than weight alone.
