BMI Calculator

The Body Mass Index (BMI) is a formula that uses your weight and height informationto calculate your body mass.

Your BMI is your body weight in kilograms divided by the square of your height in meters ([weight in kg] ÷ [height in meters]2). The resulting number generally indicates the extent of one's obesity, as well as the degree of risk for weight-related complications.

We've included a calculator below to help you determine your own BMI.

If you are in the last category (BMI >= 40) you may qualify for weight loss surgery according to NIH guidelines. In addition, the guidelines also allow for surgery for those with a BMI >= 35 when accompanied by significant co-morbidities such as diabetes, hypertension, cardiovascular disease, and high cholesterol.
