What is BMI?

BMI (Body Mass Index) is a simple calculation using height and weight to estimate body fat levels.

Formula

BMI = Weight (kg) ÷ (Height (m)²)

BMI Categories

  • Underweight: < 18.5
  • Normal weight: 18.5 – 24.9
  • Overweight: 25 – 29.9
  • Obese: 30+

Example

If you are 170 cm and 65 kg:

  • BMI = 65 ÷ (1.70²)
  • BMI ≈ 22.5 (Normal weight)
