What Is The Body Mass Index?

Body Mass Index, or BMI, is one of several possible ways to establish ideal weight and determine if the risk for health complications due to obesity. In addition to Body Mass Index, you may use waist to hip ratio or body fat percentage to establish parameters for your ideal weight.

How do you calculate Body Mass Index?

BMI is a measurement of your weight in comparison to your height. In general, a person who is taller should weigh more than a person who is shorter. Take your weight in pounds times 703. Divide that by the square of your height in inches.

For example, let’s look at a 6ft tall person weighing 190 pounds.

190 (weight) x 703 = 133570
72 x 72 (height in inches squared) = 5184
133570 / 5184 = 25.76

The body mass index for a 6ft tall person weighing 190 lbs. would be 25.76.
