How to Calculate BMI?

BMI = weight (kg) / (height (m))². For example, if you weigh 70kg and your height is 1.75m, your BMI would be 22.86 which falls in the normal weight category.

BMI Categories:

  • Underweight: BMI less than 18.5
  • Normal weight: BMI 18.5 to 24.9
  • Overweight: BMI 25 to 29.9
  • Obese: BMI 30 or greater

Remember that BMI is just one indicator of health. Always consult with a healthcare professional for personalized medical advice.
