❓ FAQ

How many ml is 1 litre?▼

1 litre = 1,000 millilitres exactly. This is the most fundamental volume conversion — the metric system is based on multiples of 10, making it beautifully simple.

How many litres is 1 US gallon?▼

1 US gallon = 3.78541 litres. Note: the UK gallon is different — 1 UK (Imperial) gallon = 4.54609 litres. Always check which gallon is being used, especially for fuel economy calculations.

How many cups in a litre?▼

1 litre = approximately 4.227 US cups. Or 1 US cup = approximately 236.6 ml. For cooking, a rough guide is 1 litre = about 4 cups (slightly more than 4 precisely).

How many fluid ounces in a litre?▼

1 litre = 33.814 US fluid ounces. Or about 35.195 UK fluid ounces (slightly different). A standard water bottle is 500 ml = about 16.9 US fluid ounces.

What is the difference between a US gallon and UK gallon?▼

A US gallon = 3.785 litres. A UK (Imperial) gallon = 4.546 litres. The UK gallon is about 20% larger than the US gallon. This matters for fuel efficiency: a UK car doing 40 mpg (miles per gallon) is NOT the same as a US car doing 40 mpg!
