The formula for calculating BMI is:
weight in pounds / (height in inches)2
Weight — This is the weight of your body, measured in kilograms or pounds. You don’t need to convert this number since both measurements are accepted by the equation
Height — Your height should be measured using feet and inches. For example, someone who is 5 feet 8 inches tall would use an answer of 70.5 inches for their height
Determining Your Weight Status Using BMI Categories If you want to put your result into perspective, you can look up what category it falls under. A healthy weight has a corresponding BMI of 18.5-25; overweight has a range of 25-29; obese has a range of 30-39; and morbidly obese has more than 40.
To find your weight status, look up your BMI number in the table below.
BMI of 18.5-24.9: Healthy weight
BMI of 25-29.9: Overweight
BMI of 30 or greater: Obese
