Body Mass Index Calculator

This Body Mass Index (BMI) calculator uses a mathematical ratio of weight and height to determine whether or not your weight falls within a healthy range. To use the calculator, click the radio button for either centimeters/kilograms or inches/pounds, then enter your height and weight, then click the "Calculate" button.

Keep in mind that BMI can be misleading because someone can have a high BMI but still be healthy with low body fat. For instance, people who are muscular often have a high BMI because of the weight of the muscle. And people who have large frames may have a high BMI even if they don't have a lot of body fat.
