What is BMI?

BMI (Body Mass Index) is a simple calculation that uses your height and weight to estimate whether you have a healthy body weight.

It is widely used by health professionals to categorize individuals into different weight ranges.

BMI Formula Explained

The BMI formula is:

BMI = Weight (kg) ÷ Height² (m²)

This means your weight in kilograms is divided by the square of your height in meters.

Instead of calculating manually, you can use an online tool for quick and accurate results.
