Example Calculation
Let’s understand how BMI is calculated with an example.
Given:
- Weight = 70 kg
- Height = 170 cm
Step 1: Convert Height to Meters
Height = 170 ÷ 100 = 1.7 m
Step 2: Apply Formula
BMI = 70 ÷ (1.7 × 1.7)
Step 3: Final Calculation
BMI = 70 ÷ 2.89 = 24.22
Result:
- BMI Value: 24.22
- Category: Normal weight
