Measure BMI
BMI is a screening measure that relates body weight to height. Enter consistent height and weight units to get the correct result.
Formula: BMI = weight (kg) ÷ height² (m²)
Enter age, body measurements, dates, or activity choices exactly as requested. These calculators estimate a result from the inputs rather than directly measuring a physical condition.
Repeat the calculation with the same values to confirm the output, then review the unit and method before interpreting the number.

Results are estimates based on the information entered and the method used. If you have a medical concern or are making a health-related decision, consult a qualified healthcare professional.
