BMI Calculator

Calculate your Body Mass Index using your height and weight. This simple tool helps you understand whether your result falls into the underweight, normal, overweight, or obese category.

What Is BMI?

BMI stands for Body Mass Index. It is a simple calculation that compares your weight to your height. It is commonly used as a quick screening tool to estimate whether a person is in a lower, moderate, or higher weight range.

BMI does not directly measure body fat, muscle mass, or overall health, but it can still be a useful starting point for understanding your weight category.

How BMI Is Calculated

The formula is:

BMI = weight (kg) ÷ height (m)²

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

70 ÷ (1.70 × 1.70) = 24.22
