BMI Formula Explained
The BMI Measurement Calculator uses a standard formula recognized globally by health organizations.
BMI Formula:
BMI=height(m)2weight(kg)
Where:
- Weight is measured in kilograms (kg)
- Height is measured in meters (m)
Step-by-Step Formula Breakdown
- Convert height from centimeters to meters:
- Height (m) = Height (cm) ÷ 100
- Square the height value:
- Height × Height
- Divide weight by squared height:
- BMI = Weight ÷ (Height²)
Example BMI Calculation
Let’s understand with a real-life example:
Example:
- Height: 170 cm
- Weight: 65 kg
Step 1: Convert height
170 ÷ 100 = 1.7 meters
Step 2: Square height
1.7 × 1.7 = 2.89
Step 3: Apply formula
BMI = 65 ÷ 2.89 = 22.49
Result:
- BMI = 22.49
- Status = Normal Weight
This means the person is in a healthy weight range.
