1
Multiply your height (in inches) by itself, using your calculator. For example, if you are 73 inches tall, multiply 73 by 73 to get 5,329.
-
2
Divide your weight (in pounds) by your squared height. If your squared height is 5,329, and you weigh 203 lbs., divide 203 by 5,329 to get .0381.
-
3
Multiply your quotient (result of division) by 703. The result is your BMI. Multiplying a quotient of .0381 by 703 results in a BMI of 26.8.

Compare your BMI to the Centers for Disease Control's standards. Below 18.5 indicates an underweight body mass; 18.5 to 24.9 indicates a normal body mass; 25.0 to 29.9 indicates an overweight body mass; and over 30.0 indicates an obese body mass. A BMI of 26.8 indicates barely overweight.
