What Is BMI (Body Mass Index)?

Body Mass Index (BMI) is a simple health indicator that compares your weight and height to determine whether you are underweight, normal, overweight, or obese.

It is widely used by doctors, fitness experts, and health organizations as an initial screening tool to assess potential health risks related to body weight.

How BMI Is Calculated

BMI is calculated using the following formula:

BMI = Weight (kg) ÷ Height (m²)

For example, if your weight is 70 kg and height is 1.70 meters, your BMI would be:

70 ÷ (1.70 × 1.70) = 24.22

This BMI calculator performs the calculation automatically and shows your health category instantly.

BMI Categories (WHO Standard)

Below 18.5 – Underweight
18.5 – 24.9 – Normal (Healthy)
25 – 29.9 – Overweight
30 and above – Obese

Maintaining a normal BMI range helps reduce the risk of lifestyle diseases such as diabetes, heart disease, and high blood pressure.
