What Is BMI (Body Mass Index)?
Body Mass Index (BMI) is a numerical value derived from your weight and height. It is used to classify individuals into different health categories such as underweight, normal weight, overweight, or obese.
BMI does not directly measure body fat, but it provides a reliable estimate of whether your body weight is appropriate for your height.
Why BMI Is Important for Health

1. Monitor Your Health
BMI helps you track whether your weight is within a healthy range.
2. Prevent Health Risks
High or low BMI can indicate potential health issues like heart disease, diabetes, or malnutrition.

BMI Formula Explained
The BMI calculation is based on a simple mathematical formula:
BMI Formula
BMI=Height(m)2Weight(kg)
Where:
- Weight is in kilograms
- Height is in meters
Since height is often given in centimeters, we convert it:
Height(m)=100Height(cm)
Then BMI is calculated using the squared height value.
BMI Categories Explained
Once BMI is calculated, it falls into one of the following categories:
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25 – 29.9 | Overweight |
| 30 and above | Obese |
These categories help determine whether a person needs to gain or lose weight.
Example of BMI Calculation
Let’s understand it with a simple example:
Given:
- Weight = 70 kg
- Height = 170 cm
Step 1: Convert Height
Height in meters = 170 ÷ 100 = 1.7 m
Step 2: Apply Formula
BMI=1.7270
Step 3: Calculate
BMI = 70 ÷ 2.89 = 24.22
Step 4: Result
- BMI = 24.22
- Category = Normal weight
This means the person is within a healthy weight range.
