BMI is your weight (in kilograms) over your height squared (in centimeters). You can find a BMI calculator on the internet, but if you would like to do it yourself, then here is how! To convert your weight in pounds to kilograms, and your height in feet to centimeters you must do the following:
- Multiply the weight in pounds by 0.45 (the metric conversion factor)
- Multiply the height in inches by 0.025 (the metric conversion factor)
- Square the answer from step 2
- Divide the answer from step 1 by the answer from step 3
This is your BMI.
You could also use the BMI Calculator from the US Department of Health & Human Services.
