How to Figure Your Body Mass Index

You can use Body Mass Index (BMI) to determine whether you’re at a healthy weight or overweight and, therefore, at a greater risk of developing weight-related health problems. BMI strongly correlates to the total fat on your body, and best of all, it’s easy to determine and is applicable to all adults.

Follow these steps to calculate your BMI:

  1. Convert your weight from pounds to kilograms.

    Your weight (in pounds) ÷ 2.2 = your weight (in kilograms). For example, 132 pounds ÷ 2.2 kilograms = 60 kilograms.

  2. Convert your height from inches to meters.

    Your height (in inches) ÷ 39.37 = your height (in meters). For example, 65 inches ÷ 39.37 meters = 1.65 meters.

  3. Calculate your Body Mass Index.

    Your weight (in kilograms) ÷ [your height (in meters) x your height (in meters)] = BMI. For example, 60 kilograms ÷ (1.65 meters x 1.65 meters) = 22.03.

BMI is usually calculated in kilograms and meters, but if you feel more comfortable using pounds and feet, this formula will work for you:

After calculating your BMI, you can determine whether you’re at a healthy weight:

  • Healthy weight: BMI of 19 to 24.9

  • Overweight: BMI of 25 to 29.9

  • Obese: BMI of 30 and above
