BMI Calculator

Calculate your Body Mass Index (BMI).

What is a BMI Calculator?

A BMI Calculator is a simple health tool that calculates your Body Mass Index (BMI) using your height and weight. BMI is a numerical value that helps determine whether a person is underweight, normal weight, overweight, or obese according to standard health guidelines.

How This Tool Works

The calculator uses a mathematical formula that divides a person's weight by the square of their height. Once you enter your height and weight, the tool instantly calculates your BMI and compares it with standard BMI categories to show your health status.

Example

For example, if a person weighs 70 kilograms and has a height of 1.75 meters, the BMI calculator will compute their BMI as approximately 22.9, which falls within the normal or healthy weight range.

Why Use a BMI Calculator?

BMI calculators help people quickly understand whether their body weight is within a healthy range. They are commonly used for health assessments, fitness planning, and medical evaluations. Instead of calculating BMI manually, this tool provides instant and accurate results.
