Adult body surface area estimate
Estimate adult body surface area with the Mosteller formula. Educational geometry only; no medication dosing.
How it works
Mosteller BSA (m²) = sqrt((height in cm × weight in kg) / 3600). For 180 cm and 80 kg, the estimate is 2 m².
Before using the result
- Check the selected mode, units and input values before using the result.
- Read the assumptions and rounding rules; compare the worked example with your intended calculation.
- A numerical result does not supply missing context or change the stated limitations.
Limitations
This adult educational estimate does not determine a medication dose, burn area or treatment. Children, unusual body proportions and clinical dosing require professional assessment and the relevant protocol.
Frequently asked questions
What should I verify before using this result?
Check the input values, units, dates and assumptions. Compare the method and its stated limits with the source relevant to your task.
Why might the finished result differ?
Results depend on the entered data and the model’s assumptions. Rounding, changing conditions or omitted factors can affect the comparison. Read the limitations before using the result.
