When you need to convert US teaspoons to Imperial gallons

  • Scaling recipes between metric millilitres and US cups, pints or fluid ounces.
  • Comparing fuel prices and tank capacities between countries.
  • Working out paint, fertiliser or pool chemical quantities from instructions written for another market.

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 US teaspoon = 0.001084 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.

How these units are defined

  • US teaspoon (tsp): One third of a US tablespoon, about 4.93 mL. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
  • Imperial gallon (imp gal): Exactly 4.54609 liters — the gallon used in the UK and historically in Canada. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
