BMI Calculation Formula and Example
BMI Formula
BMI = weight (kg) ÷ (height (m))²
For US units: BMI = (weight (lbs) × 703) ÷ (height (in))²
How to Calculate BMI
Let's calculate BMI for a person who is 170 cm tall and weighs 65 kg:
1. Convert height to meters: 170 cm = 1.70 m
2. Square the height: 1.70 × 1.70 = 2.89
3. Divide weight by squared height: 65 ÷ 2.89 = 22.49
Result: BMI = 22.49 (Normal Weight)
