Convert gallons to cups
cups = gallons × 16
One gallon is 16 cups, so multiply by 16 to convert. That factor is exact by definition. These are US customary measures. An imperial (UK) gallon is 4.54609 L against the US gallon's 3.785411784 L, and the imperial pint, quart and fluid ounce differ too, so UK figures will not match. This is the US customary cup of 236.588 mL. Nutrition labels use a 240 mL cup and metric recipes a 250 mL one; the difference is under 6%, which matters for baking and not much else.
