- Convert your weight in pounds to your weight in kilograms by dividing your weight in pounds by 2.2.
- Convert your height in inches to your height in meters by multiplying your height in inches -- not feet -- by 0.0254. (If you are 5 feet tall, your height is 60 inches, or 1.52 meters. If you are 6 feet tall, your height is 72 inches, or 1.83 meters.)
- Square your height in meters (that is, multiply your height in meters by itself).
- Divide your weight in kilograms by the number you obtained in the previous step.
