About this calculator
Body Mass Index (BMI) is calculated as weight in kilograms divided by height in metres squared (kg/m²). The formula was developed by Belgian mathematician Adolphe Quetelet in the 1830s as a statistical tool for population studies, not individual diagnosis.
BMI is grouped into four standard categories: Underweight (<18.5), Normal weight (18.5–24.9), Overweight (25–29.9), and Obese (≥30). Because BMI doesn't directly measure body fat, it doesn't account for muscle mass, bone density, age, or fat distribution — two people with the same BMI can have very different body compositions.
