What is BMI?
Body Mass Index (BMI) is a measure of body fat based on height and weight. Formula: BMI = weight (kg) / [height (m)]². Categories: Underweight <18.5, Normal 18.5-24.9, Overweight 25-29.9, Obese 30+. While useful, BMI doesn't distinguish muscle vs fat, so athletes may show higher. Always consult healthcare professionals for medical advice. This tool is for informational purposes only.
