How to Calculate BMI

Definition

BMI (Body Mass Index) is a measure that uses your height and weight to determine if your weight is in a healthy range. It’s commonly used for adults as a quick indicator of possible health risks.

Formula

BMI = Weight (kg) / [Height (m)]²

Example

If you weigh 70 kg and your height is 1.75 m:

• BMI = 70 ÷ (1.75 × 1.75) ≈ 22.86
• This generally falls within the normal range (18.5–24.9).
