Calculate your Body-mass Index
Your body-mass index ("BMI") measures your height/weight ratio. It is your weight in kilograms divided by the square of your height in meters.

For instance, if your height is 1.82 meters, the divisor of the calculation will be (1.82 * 1.82) = 3.3124. If you weigh 70.5 kilograms, then your BMI is 21.3 (70.5 / 3.3124).

People with BMIs between 19 and 22 live longest. Death rates are noticeably higher for people with indexes 25 and above.

This is the American version of the calculation. Enter your height (in feet and inches) and weight (in pounds) in the boxes below, and then click "calculate". These are converted to metric values to figure your BMI.

Also note: if you are exactly 5 feet or 6 feet tall, put a 0 in the inches box. The result is "infinity" if you leave the inches box empty.

Remember, you can have a high BMI and a low body fat percentage. BMI is only one measure of your health. Body fat percentage, blood pressure, resting heart rate, cholesterol and other measurements are at least as important as BMI. You need to get the whole picture you should research the subject and be evaluated professionally for a complete and accurate picture of your health.
