Example BMI Calculation

Example:

  • Weight: 65 kg

Step 1: Convert height into meters

170 cm = 1.70 m

Step 2: Apply formula

BMI = 65 ÷ (1.70 × 1.70)
BMI = 65 ÷ 2.89
BMI = 22.49

Result:

  • BMI Value: 22.49
  • Status: Normal Weight

This means the person has a healthy weight according to their height.
