Answer : The easiest way to calculate BMI, especially for the math-phobic, is to enter your height and weight into one of the many BMI calculators on the Web, such as the National Heart, Lung and Blood Institutes page at www.nhlbisupport.com/bmi. If youd rather do it youself, the standard formula requires you to convert your weight from pounds into kilograms (divide by 2.2) and height from inches into meters (divide by 39.37). To figure BMI, divide your weight in kilograms by your height in meters squared. If youd rather skip the metric system, try this: weight in pounds x 703 / height in inches 2. Either way, for example, a person whos 165 pounds and 5-foot-9 (69 inches) has a BMI of 24.4.
