Calculating Your BMI

Whether you are trying to lose weight or you are working on weight management, one of the first steps to a healthier you is knowing whether or not you fall into a weight range that is healthy for you. The best way to determine if you are a healthy weight is by using a number called your BMI. The BMI (body mass index) is a mathematical formula that uses your weight and height to predict the potential development of health problems related to excess weight.

BMI Formula

Using this formula, you can determine your BMI. The first step is to multiply your weight in pounds by 705. Next, divide that number by your height in inches. Finally, take the resulting number and divide it by your height in inches again.

BMI = 705 x weight (in pounds)
             (height in inches)2

What it Means

The number that you get after using this formula is your BMI. The list below will help you understand the connection between your BMI and your weight.

BMI

Weight

Below 18.5

Underweight
Between 18.5 and 24.9         Normal
Between 25 and 29.9 Overweight
30 or higher Obese

If your BMI is not within the normal range, see your health care provider about how you can work toward a healthier weight for your height. Now that you know how to calculate your BMI, you are on your way to a healthier you!
