How to Calculate BMI

BMI (Body Mass Index) is a number derived from an individual's weight and height. It is used to categorize underweight, normal weight, overweight, or obese based on the values calculated.

Steps:

  • Convert your height into inches: Total inches = (feet * 12) + inches
  • Calculate BMI: BMI = (weight in pounds) / (height in inches ^ 2) * 703

Example Formula:

If your weight is 150 pounds and height is 5 feet 6 inches (66 inches), the formula will look like this:

BMI = 150 / (66 * 66) * 703 = 24.2

What is it used for?

BMI is used to determine if an individual is at a healthy weight. A BMI between 18.5 and 24.9 is considered normal.
