Frequently asked questions
How many cups are in a quart?
4 — a gallon is 4 quarts, each quart is 4 cups, so the full chain multiplies out to 16 cups per gallon.
Where is this conversion most commonly needed?
Recipe scaling, especially for large-batch recipes measured in gallons that need converting down to cup measurements.
Is a US gallon the same as an imperial gallon?
No — an imperial gallon is larger, so this conversion applies specifically to the US gallon and cup definitions.
