## BMI Prime

Devised all the way back in way back in 1830, BMI is a single figure 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 Prime is a variation of the Quetelet index. Put simply, 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 defined as being overweight. ## Work it out!

Use the body mass formula to get your bmi

- BMI = weight(kilograms) / height
^{2} (metres^{2}) (Metric Units) - BMI = 703 . weight(pounds) / height
^{2} (inches^{2}) (Imperial Units)
