How many cups are in a gallon? (complete measurement and conversion guide)
How many cups are in a gallon? Volume conversions might be challenging to memorize. That is why we made this comprehensive guide on conversion from cups to gallons and to pints and quarts.
What is a gallon?
Before we discuss how many cups are in a gallon, it is pertinent for us to understand the types of gallons available and how they relate and differs.
The gallon is a volume measurement used in the United States.
Have you heard of:
 A liquid gallon?
 A dry gallon?
 US gallon?
 UK gallon?
What do they mean?
The two standard types of gallon, a US gallon and a UK gallon (also known as a royal gallon), are made up of16 cups.
So a US gallon, which is also a liquid gallon, has 16 cups.
A liquid gallon is now considered a standard gallon because a dry gallon is no longer useful for these calculations. A dry gallon has become a standard for estimating another unit, bushel, for dry fixings.
A dry gallon contains 18.61 cups. But standard practice dictates that a liquid gallon contains 16 cups.
According to Wikipedia, “the gallon is a unit of volume in imperial units and United States customary units. Three different versions are in current use: the imperial gallon (imp gal), defined as 4.54609 liters, which is or was used in the United Kingdom, Ireland, Canada, Australia, New Zealand, and some Caribbean countries;
the US gallon (US gal), defined as 3.785411784 L, (231 cubic inches), which is used in the US and some Latin American and Caribbean countries; and the US dry gallon (“usdrygal”), defined as 1⁄8 US bushel (exactly 4.40488377086 L). There are two pints in a quart and four quarts in a gallon. Different sizes of pints account for the different sizes of the imperial and US gallons.”
How many cups are in a gallon?
Estimating cups in a gallon is simple.
Formula:
1 US gallon = 16 US cups.
To get how many cups are in gallons, multiply the volume value (in gallons) by 16.
See below for other conversion factors for cups to gallons:

1 US fluid gallon = 16 US cups

1 US dry gallon = 18.6 US cups

1 Imperial gallon = 18.18 metric cups

1 gallon of water = 16 cups

1 gallon of milk = 16 cups

1 gallon of coffee = 20 cups of coffee beans

½ gallon of water = 8 cups

½ gallon of milk = 8 cups

½ gallon of coffee = 8 cups
How many liters make a gallon?
Formula:
1 gallon = 3.78 liters.
How many ounces are in a cup?
Formula:
1 US cup = 8 US fluid ounces.
How many cups are in a pint?
Formula:
1 US pint = 2 US cups.
How many cups are in a quart?
Formula:
1 quart = 4 cups.
In Summary:
Remember that: 8 ounces = 1 cup; 2 cups = 1 pint. Therefore, 16 ounces = 1 pint.
Measurement Conversion Table
 1 US Gallon = 4 Quarts = 8 Pints = 128 ounces = 16 US cups
 1 Quart = 2 Pints = 32 ounces = 4 US cups
 1 Pint = 16 ounces = 2 US cups
 Threefourths of a cup = 12 tablespoons
 Half of a cup = 8 tablespoons 4 ounces
 Onethird of a cup = 5 tablespoons and 1 teaspoon
 Onefourth of a cup = 4 tablespoons 2 ounces
 Oneeighth of a cup = 2 tablespoons
 1 tablespoon = 0.90 cubic inches
 1 Quart = 2 Pints
 1 Pint = 2 cups, 32 Ounces
 1 ounce = 2 tablespoons
 1 tablespoon = 3 teaspoons
