How this calculator works
This calculator converts a volume value between metric units such as litres and millilitres and imperial or US customary units such as gallons, cups and fluid ounces. Litres are the standard Australian unit for fuel, drinks and cooking, while gallons and cups are common in American recipes and equipment specifications.
Frequently asked questions
Is a US gallon the same as a UK gallon?
No, a US gallon is about 3.785 litres while a UK (imperial) gallon is about 4.546 litres, so this calculator treats them separately.
What volume unit does Australia use for fuel?
Australia sells fuel by the litre, so this converter is handy for comparing to gallon-based fuel figures from other countries.
Can I convert millilitres to cups for a recipe?
Yes, select millilitres as the source and US cups as the target to convert an overseas recipe's liquid measurements.
