Maintaining a healthy body weight is important for overall fitness and long-term health. Whether you want to lose weight, gain muscle, or maintain your current body shape, the first step is understanding your BMI.

A BMI Calculator (Body Mass Index Calculator) helps you check whether your weight is underweight, normal, overweight, or obese based on your height and weight.

In this detailed guide, we will explain what BMI is, how it is calculated, and how you can use an online BMI Calculator easily.

What is BMI?

BMI stands for Body Mass Index.
It is a simple numerical value calculated using your height and weight.

BMI helps determine whether your body weight is healthy for your height.

It is widely used by doctors, fitness experts, and health organizations to assess body weight categories.

BMI Formula

BMI is calculated using the following formula:

Metric Formula:

BMI = Weight (kg) / Height² (meters)

Example:

If your weight is 70 kg and height is 1.75 meters:

BMI = 70 / (1.75 × 1.75)
BMI = 22.86

This falls under the “Normal weight” category.

Manual calculation can be confusing. That’s why using an online BMI Calculator is the easiest and fastest way.
