This article will explain everything about BMI calculation, its formula, how to use the calculator, examples, and frequently asked questions to help you better understand your health.
What Is BMI (Body Mass Index)?
BMI (Body Mass Index) is a numerical value calculated from a person’s weight and height. It is used to categorize individuals into different health groups such as underweight, normal weight, overweight, or obese.
BMI does not measure body fat directly, but it provides a reliable screening tool for most people to understand their weight status.

1. Health Monitoring
BMI helps identify whether you are at risk of health conditions such as diabetes, heart disease, or hypertension.
2. Weight Management
It helps you understand if you need to gain, lose, or maintain your current weight.
3. Fitness Planning
Fitness trainers use BMI to design workout and diet plans.

BMI results are classified into standard health categories:

| 18.5–24.9 | Normal | Healthy weight range |
| 25–29.9 | Overweight | Lifestyle changes recommended |
| 30+ | Obese | Medical consultation advised |
Example of BMI Calculation
Let’s understand BMI with a real-life example.
Given:
- Weight = 70 kg
- Height = 170 cm
Step 1: Convert Height
Height = 170 ÷ 100 = 1.7 m
Step 2: Apply BMI Formula
BMI=1.7270
Step 3: Solve
BMI = 70 ÷ 2.89 = 24.22
Result:
- BMI Value: 24.22
- Category: Normal
