BMI Calculator: Body Mass Index

What is the BMI scale and what it measures?

BMI stands for Body Mass Index and is a measurement of how healthy you are in relationship between two prominent body metrics: your weight and height. It is calculated by dividing a person’s weight in kilograms by the square of height in meters.
A high BMI may indicate high body fatness but BMI does not diagnose health of an individual.

What is BMI prime?

BMI Prime is a ratio of a person’s BMI to the upper-level weight limit of “healthy weight”. It is intended to give a quick answer as to how far an individual differs from upper weight limits, as well as an easy comparison between people whose upper BMI weight limits are different. A BMI Prime between 0.74 – 1.00 is generally considered optimal for health.
