BMI Calculator
Calculate body mass index from weight and height in metric or imperial units.
BMI is an adult screening tool: it does not measure body composition and may not represent athletes or pregnancy well.
Estimated result
Enter valid weight and height.
How BMI is calculated
BMI divides weight in kilograms by squared height in meters. It is an adult screening reference, not a direct fat measurement.
Result limitations
Athletic build, pregnancy, age, and fat distribution can limit its usefulness. Consider other measurements too.
Frequently asked questions
Does BMI diagnose health?
No. It classifies a mathematical ratio and does not diagnose disease.
Is personal data sent to a server?
No. Calculations run locally in your browser and these values are not stored by default.
Can I use the result as medical advice?
No. It is an educational reference and does not replace individual assessment.
