## BMI Prime

Devised in way back in 1830, the BMI is used to as a way of measuring a person's body shape. Put simply, it is calculated by dividing the body's weight by the square of their height. Eg: Kilograms: weight, divided by Metres (Meters): height. Bmi is a variant of the Quetelet index. If you have a Prime of less than 0.74, you are underweight. If your prime is more than 0.74 and less than 1.00, your weight is ideal. If your BMI prime is more than 1 you are probably overweight.

Use the body mass formula to get your bmi
• BMI = weight(kilograms) / height2 (metres2)         (Metric Units)
• BMI = 703 . weight(pounds) / height2 (inches2)         (Imperial Units)
