Body Mass Index (BMI) is a simple way to assess whether your weight is healthy for your height. While not perfect, it's a useful screening tool used by health professionals worldwide.

📐 The BMI Formula

BMI is calculated using this formula:

BMI = weight (kg) ÷ height² (m²)

Example: If you weigh 70 kg and are 1.75 m tall:
70 ÷ (1.75 × 1.75) = 22.86
