What is BMI?

BMI, or Body Mass Index, is a simple calculation based on your height and weight. It is widely used as a quick screening tool to categorize adults into weight categories: underweight, normal weight, overweight, or obese.

How is BMI calculated?

BMI = Weight (kg) ÷ Height (m)²

Example: If you weigh 65 kg and are 1.70 m tall:

65 ÷ (1.70 × 1.70) = 22.5

BMI Categories

18.5 – 24.9 — Normal
