About the Cups to Gallons Calculator

The US cup and the US gallon are both customary cooking and beverage volume units. Since a US gallon holds exactly 128 fluid ounces and a cup holds 8 fluid ounces, exactly 16 cups make up one gallon.

Formula: Gallons = Cups ÷ 16

Useful for scaling large-batch recipes, beverage dispensers and bulk liquid measurements.
