Frequently Asked Questions
How many metric cups are in 1 gallon?
1 gallon equals approximately 15.14 metric cups, each metric cup being a clean 250 milliliters.
Is the metric cup the same size as the US cup?
No, the metric cup at 250 milliliters is slightly larger than the US customary cup, which is about 236.6 milliliters, so recipes aren't perfectly interchangeable between the two.
Which countries use the metric cup?
Australia, New Zealand, and several other countries that have fully adopted the metric system for cooking measurements standardize on the 250-milliliter metric cup.
Is this based on the US gallon?
Yes, this converter uses the US liquid gallon (3.785411784 liters) rather than the larger UK imperial gallon, so results would shift slightly if you mean that unit instead.
