- Mixing US and Imperial liquid measures. The Imperial gallon and pint are about 20% larger than their US counterparts, which is enough to ruin a recipe or misstate fuel economy.
- Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.
How precise does the answer need to be?
