What is the BMI Prime Calculator?

BMI Prime is a ratio of your BMI to a standard reference BMI of 25 (the upper bound of the healthy range). A BMI Prime of 1.0 means your BMI exactly equals 25; values below 1.0 indicate underweight or healthy weight, while values above 1.0 indicate overweight or obesity.
