Common mistakes to avoid
- Dividing when you should multiply. Because 1 US tablespoon = 0.003253 Imperial gallons, the answer should be smaller than the number you started with.
- 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?
Cooking tolerates rounding to the nearest 5 mL or quarter cup. Dosing, chemistry and pool treatment do not — keep the full converted value there.
