BMI Calculator
Calculate Body Mass Index with a clear category and practical interpretation.
This calculator turns your height and weight into a Body Mass Index — a quick screening number with a category. Treat it as one signal alongside trend, waist, and behavior, not as a diagnosis. BMI does not separate muscle from fat, so use the category as context, not a verdict.
