What Is BMI (Body Mass Index)?
Body Mass Index (BMI) is a numerical value derived from a person’s weight and height. It is widely used by healthcare professionals to categorize individuals into different weight groups.
BMI does not directly measure body fat but provides a general indication of whether your body weight is healthy for your height.
BMI Categories:
- Underweight
- Normal weight
- Overweight
- Obese
These categories help assess potential health risks related to weight.
Importance of BMI in Daily Life
Understanding your BMI is important for several reasons:
1. Health Monitoring
BMI helps you keep track of whether you are within a healthy weight range.
2. Disease Prevention
High or low BMI values can indicate risks for diseases such as diabetes, heart disease, and malnutrition.

BMI Formula Explained
The BMI formula is straightforward and widely used across the world.
BMI Formula:
BMI=Height(m)2Weight(kg)
Where:
- Weight is measured in kilograms
- Height is measured in meters
Since the calculator uses centimeters, height is converted into meters before calculation.
Height Conversion:
Height(m)=100Height(cm)
Step-by-Step Calculation Process
To understand how BMI is calculated, let’s break it down:
Step 1: Convert Height
If your height is 170 cm:
Height in meters = 170 ÷ 100 = 1.7 m
Step 2: Square the Height
1.7 × 1.7 = 2.89
Step 3: Divide Weight by Height²
If your weight is 65 kg:
BMI = 65 ÷ 2.89 = 22.49
Final BMI = 22.49 (Normal Weight)
BMI Categories Explained
The calculator automatically categorizes your BMI result:
1. Underweight (BMI < 18.5)
You may need to gain weight for better health.
2. Normal Weight (BMI 18.5 – 24.9)
This is considered a healthy range.
3. Overweight (BMI 25 – 29.9)
You may need to adjust diet and exercise habits.
4. Obese (BMI 30 or above)
Higher risk of health issues; medical guidance is recommended.
Example BMI Calculation
Let’s take a practical example:
Input:
- Weight = 80 kg
- Height = 175 cm
Step 1: Convert height
175 ÷ 100 = 1.75 m
Step 2: Square height
1.75 × 1.75 = 3.06
Step 3: Apply formula
BMI = 80 ÷ 3.06 = 26.14
Result:
- BMI = 26.14
- Category = Overweight
