Common questions
Are US gallons and UK (imperial) gallons the same?
No. This calculator uses US liquid gallons (3.785 L). A UK imperial gallon is larger — about 4.546 L. Fuel economy labels and recipes may use different gallon types depending on the country.
How many liters fit in a standard US gas can?
A common 5-gallon gas can holds about 18.9 liters. For two-stroke fuel mixes (e.g. 50:1), measure gasoline in one unit throughout — do not mix gallons and liters in the same ratio calculation.
My car lists fuel tank size in liters abroad — how does that compare to gallons?
Divide liters by 3.785 for US gallons. A 60 L tank holds about 15.9 US gal. US EPA fuel-economy figures use US gallons; European labels use liters per 100 km.
Do recipe “cups” convert cleanly to liters?
US customary cups (about 237 mL each) differ from metric cups (250 mL) used in some countries. For liquids, convert the stated cup volume to mL or liters first, then to gallons if needed.
