About BMI

What is BMI?

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It's calculated by dividing weight in kilograms by height in meters squared.

BMI Formula:

  • Metric: BMI = weight (kg) / [height (m)]²
  • Imperial: BMI = [weight (lb) / height (in)²] × 703

Important Notes:

  • BMI is a screening tool and not a diagnostic measure of body fatness or health
  • Athletes and very muscular individuals may have high BMI despite low body fat
  • BMI may not accurately reflect health risks for older adults
  • Always consult with healthcare professionals for personalized health advice
