About BMI Calculator
Body Mass Index (BMI) is a general screening measure that estimates body fat based on height and weight, calculated with a standard, widely-used formula. It's a useful quick reference point, but it's not a full health diagnosis on its own.
BMI has known limitations — it doesn't distinguish muscle mass from fat, for example, so a very muscular person may show a higher BMI without actually carrying excess fat. It's best treated as one general indicator alongside other health measures, not a definitive assessment by itself.
