How to Calculate your BMI

How To Calculate Your BMI

Body Mass Index is an indicator of body fatness. We tell you how to calculate body mass index (also called as Body Weight Index) before you even obsess over losing weight. It is calculated based on your weight and height. If your  height is 5’3″ and weight is 125 lbs. ( 1 kg is 2.20462 lbs)

Step 1 Multiply your  weight in pounds by 0.45

125 X 0.45 = 56.25 kgs

Step 2 Multiply the height in inches by 0.025 (1 foot is 12 inches)

63 X 0.025 = 1.575 m

Step 3 Square the answer from step 2

1.575 X 1.575 = 2.480625

Step 4 Divide answer from step 1by step 3

56.25 / 2.480625 = 22.7 which is approximately 23

A BMI of:

  • 19 or less is underweight

  • 19 -25 is ideal weight

  • 25-30 is overweight

  • 30 or higher is obese


An overweight or obese weight index means it is time to get fitter though exercise and a healthy diet.
