A.0.1—Units in calculations

Write the quantity, unit and time or area basis before calculating. Convert units first, then substitute values and report a final answer with the correct magnitude and significant figures.

Convert cm³ to dm³ only after identifying the required output; a cardiac output of 3,750 cm³ min⁻¹ is 3.75 dm³ min⁻¹.

A numerically plausible answer with incompatible units is still wrong.
