Below, you will find information of how to find out how many cups there are in "x" gallons, including the formulas and example conversions.
The converter and the tables are based on US fluid gallons and US cups.
How many cups in a gallon?
There are 16 cups in a gallon. To convert gallons to cups, multiply the gallon value by 16.
For example, to find out how many cups in a half gallon, multiply 16 by 0.5, that makes 8 cups in a half gallon.
gallons to cups formula
cup = gallon * 16
How to convert cups to gallons?
1 Cup (c) is equal to 1/16 of a gallon (gal). To convert cups to gallons, divide the cup value by 16.
For example, to convert 32 cups to gallons, divide 32 by 16, that makes 2 gallons in 32 cups.
cups to gallons formula
gallon = cup * 0.0625
gallon = cup / 16
What is a Gallon?
Gallon is an imperial and United States Customary measurement systems volume unit. 1 Gallon = 16 Cups. The symbol is "gal".
There are three types of gallons, US Customary fluid and dry gallons and the Imperial gallon. There are a few commonly accepted sizes for cups such as US cup, Metric cup, Imperial cup and the Canadian cup. So, depending on what types of gallons and cups are used, the answer to the question of how many cups in a gallon might be different. If you are converting from US fluid gallons to US cups, then there are 16 cups in a gallon. If the conversion is between US dry gallons and US cups, then there are 18.618 US cups in a US dry gallon.
The list of conversion factors from gallons to cups:
- 1 US fluid gallon = 16 US cups
- 1 US dry gallon = 18.618355 US cups
- 1 Imperial gallon= 16 Imperial cups
- 1 Imperial gallon= 18.18436 Metric cups
Common conversions from gallons to cups:

What is a Cup?
Cup is a Metric and United States Customary measurement systems volume unit. 1 Cup = 1/16 Gallon. The symbol is "c".

There are 16 cups (C) in 1 gallon (gal). Cups and gallons are measurements of volume and capacity in the US customary and imperial systems of measurement. Both these systems use different definitions of the gallon, but the relationship between gallons and cups stays the same within each system.
The US additionally has a definition of the cup called the US legal cup that varies slightly in measurement from the US customary cup. This definition is used in the US specifically for nutrition labeling. Unlike the imperial cup and the US customary cup which are based on each system's definition of the gallon, the US legal cup is used as a unit on its own, and "US legal gallons" for example, are not used. Thus, a US legal cup is not equal to 16 US customary gallons. It is actually equal to 15.7725 US customary gallons.
Cups to gallons conversion
The following converter can be used to convert from cups to gallons or gallons to cups. Just enter a value in either cups or gallons to convert between the two.
Cups to gallons conversion explained
To convert between cups and gallons we need to remember the relationship between cups and gallons:
1 C =
1 gal = 16 C
Based on this relationship, we need to divide a value in cups by 16 to convert it to gallons. To convert a value in gallons to cups, we instead multiply by 16.
Examples
1. Convert 12 cups to gallons:
12 C ÷ 16 = 0.75 gal
2. Convert 2.3 gallons to cups:
2.3 gal × 16 = 36.8 cups
Note that this conversion works for cups and gallons within the same system of measurement. 1 US cup is not equal to 16 imperial gallons. If we were trying to convert these, we would need to convert the US cup to an imperial cup before applying the conversion above.
Definition: A gallon is a unit of volume specifically regarding liquid capacity in both the US customary and imperial systems of measurement. The US gallon is defined as 231 cubic inches (3.785 liters). In contrast, the imperial gallon, which is used in the United Kingdom, Canada, and some Caribbean nations, is defined as 4.54609 liters. In both systems, the gallon is divided into four quarts. Quarts are then divided into two pints and pints are divided into two cups. A cup is comprised of two gills, making one gallon equal four quarts, eight pints, sixteen cups, or thirty-two gills. Further differentiating the US and the imperial gallon, a US gill is divided into four fluid ounces, while an imperial gallon is divided into five. A US fluid ounce is therefore 1/128 of a US gallon while an imperial fluid ounce is 1/160 of an imperial gallon.
History/origin: The term gallon most closely originates from "galon" in Old Northern French and developed as a system for measuring wine and beer in England, resulting in measures such as the wine gallon, ale gallon, and imperial gallon.
Current use: In the United States (US), gallons are often used for larger containers, such as half gallon tubs of ice cream or one-gallon cartons of milk. Gallons are also widely used in fuel economy expression in the US, as well as some of its territories. The imperial gallon is used even more sparingly than the US gallon, with most countries around the world using liters when referencing fuel.
Cup (US)
Definition: A cup is a unit of volume in the imperial and United States customary systems of measurement. The metric cup is defined as 250 milliliters. One United States customary cup is equal to 236.5882365 milliliters as well as 1/16 U.S. customary gallons, 8 U.S. customary fluid ounces, 16 U.S. customary tablespoons, or 48 U.S. customary teaspoons.
Current use: The cup is typically used in cooking to measure liquids and bulk foods, often within the context of serving sizes. Actual drinking cups can vary significantly in terms of size and are generally not a good representation of this unit. Standardized measuring cups are used instead.
