Frequently asked questions
Is a US gallon the same as a UK (imperial) gallon?
No — a US gallon (3.785 L) is smaller than a UK imperial gallon (4.546 L). This calculator uses US customary units throughout.
How many cups are in a US gallon?
16 US cups make 1 US gallon.
Does this support cooking-specific units like a "stick of butter"?
No — this calculator covers standard volume units. For recipe-specific conversions, check the recipe's own measurement notes, since informal units vary by region and source.
