US Gallons to Cups

US Gallon

A US gallon (gal) is a common unit of volume used mainly in the United States for measuring liquids such as fuel, milk, and other beverages. One US gallon equals 4 quarts, 8 pints, or 128 fluid ounces, making it a practical size for everyday containers and large-scale liquid purchases. It’s widely recognized at gas stations and in grocery stores, where gallon jugs are frequently sold.

Because the US gallon differs from the Imperial gallon used in the UK, conversions can get confusing across countries. An online converter helps accurately translate gallons into liters or other units for travel, shopping, or cooking with international recipes.

Cup

A cup (c) is a popular unit of volume used mainly in the United States for cooking, beverages, and everyday household measurements. One US cup equals 8 fluid ounces or 16 tablespoons, making it a convenient size for recipes and serving portions. Because measuring cups are easy to find in most kitchens, the cup has become a standard reference in baking and cooking instructions.

Converting cups to metric units — such as milliliters or liters — can be tricky because recipes around the world use different standards. An online converter makes it simple to switch between systems and follow international cooking guides accurately.
