How to Calculate BMI

BMI (Body Mass Index) is calculated using the formula:

BMI = weight (kg) / height (m)²

Metric Example: If you weigh 70 kg and are 1.75 m tall:

  • BMI = 70 / (1.75 × 1.75)
  • BMI = 70 / 3.0625
  • BMI = 22.9 (Normal weight)

Imperial Example: If you weigh 154 lbs and are 5 feet 7 inches tall:

  • Convert to metric: 154 lbs = 69.9 kg, 5'7" = 1.70 m
  • BMI = 69.9 / (1.70 × 1.70) = 24.2 (Normal weight)

Note: BMI is a screening tool and doesn't account for muscle mass or body composition. Consult with a healthcare professional for a complete health assessment.
