Getting a feel for the scale
A converted number is easier to trust when you can picture it. These reference points let you sanity-check the result at a glance.
Imperial gallon (imp gal)
- An Imperial gallon is about 1.2 US gallons
- UK fuel prices are quoted per litre, not per gallon
Common mistakes to avoid
- Dividing when you should multiply. Because 1 Imperial gallon = 0.160544 cubic feet, 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.
