Metric BMI FormulaBMI = Weight in kilograms/height in meters x height in meters(Weight in kilograms divided by height in meters squared (kg/m2). Since height is commonly measured in centimeters, divide height in centimeters by 100 to obtain height in meters).
2. Imperial BMI Formula(Weight (lbs.) * 703) / Height (inches)2
(When using pounds and inches, the formula needs to be altered slightly. Multiply your weight in pounds by 703. Divide that by your height in inches, squared).
