Weight in pounds (lbs) divided by height in inches (in) squared and multiplied by a conversion factor of 703 (weight (lbs) / [height (in)2]x 703).

Therefore, to calculate BMI, take the weight (lbs) and divide it by height (in). Take the result of that calculation and divide it by height again. Then, multiply that number by 703. Round to the second decimal place.

An example of calculating body mass index using the BMI formula:
Weight = 200 lbs, Height = 5’8″ (68 inches)

BMI Calculation: [200 ÷ (68)2] x 703 = 30.41

Find your BMI Range below:

• Underweight 18.5 and Lower
Healthy Weight: BMI between 19 and 25
Overweight: BMI between 25 and 30
• Obese: BMI over 30
• Severely (Morbidly) Obese: BMI is 40 or more
