What Is a BMI Calculator?

A BMI Calculator is an online tool that calculates your Body Mass Index (BMI) using your height and weight. BMI is one of the most widely used methods for estimating whether an adult has a healthy body weight.

Based on your BMI result, you may be classified as:

  • Underweight
  • Healthy Weight
  • Overweight
  • Obese

The standard BMI formula is:

BMI = Weight (kg) ÷ Height² (m²)

Example:

  • Weight: 70 kg
  • Height: 1.75 m

BMI = 70 ÷ (1.75 × 1.75) = 22.86

This BMI falls within the Healthy Weight category.
