How To Calculate Your BMI
The Body Mass Index (BMI) is believed to be a good approximation of healthy weight,
as your BMI is proportional to your weight, divided by the square of your height.
Here is how you can find out what your BMI is:
Multiply your weight, in pounds, by 0.45 (example: 130 pounds x 0.45 = 58.5).
Multiply your height, in inches, by 0.025 (example: 5¹6" or 66" x 0.25 = 1.65).
Multiply the answer from step 2 by itself (example: 1.65 x 1.65 = 2.7225).
Divide the answer from step 1 by the answer from step 3 (example: 58.5 ÷ 2.7225 = 21.48).
If your body mass index rates below 21, you are underweight.
If your body mass index rates above 27, you are overweight.
A BMI of more than 40 indicates that you are obese.
