BMI Formula Explained
The BMI calculation is based on a simple mathematical formula.
Standard BMI Formula:
BMI=Height(m)2Weight(kg)
Where:
- Weight is measured in kilograms
- Height is measured in meters
Height Conversion Formula:
Height(m)=100Height(cm)
Since the calculator takes height in centimeters, it first converts it into meters before applying the formula.
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 you understand your general health condition.
Example Calculation
Let’s understand how the calculator works with a real example.
Given:
- Height = 170 cm
- Weight = 65 kg
Step 1: Convert Height to Meters
170 cm ÷ 100 = 1.70 m
Step 2: Apply BMI Formula
BMI=1.7265
Step 3: Final Calculation
BMI = 65 ÷ 2.89 = 22.49
Result:
- BMI: 22.49
- Category: Normal weight
This means the person has a healthy body weight according to BMI standards.
