What is a gallon?

The gallon has a fascinating history, with many different definitions and redefinitions throughout the years.

A gallon (abbreviation 'gal') is a unit of volume used in the USA and in some Latin American and Caribbean countries.

There are different types of gallons. The Royal gallon is scarcely used in the United Kingdom; they still use both imperial and metric systems.

A US dry gallon is equal to ⅛ US bushel, or 4.4 L. Therefore, it is about 14.1% bigger than the US fluid gallon.

Interestingly, Canadians consider the debate liter and gallon as standard units.

Imperial gallon vs. metric gallon

There are two gallon standards: the US (metric) gallon and the imperial (UK) gallon. The US gallon equals 3.785 liters and holds 16 US cups, while the imperial gallon equals 4.546 liters and holds about 18.18 imperial cups. The US gallon is a standard unit for measuring volume in America. The conversion system says that a gallon equals 3.78 liters or 16 cups.

1 US gallon = 16 US cups

1 US gallon = 3.78 liter

1 US gallon = 231 cubic inches

The imperial gallon (aka British or Royal gallon) is 20% more than the US gallon and equals 4.546 liters.

1 British gallon = 1.2 US gallon

1 British gallon = 4.546 liters

It is essential to distinguish between the US customary gallons and the imperial gallons. Why?

Because the US gallon is smaller than the UK one, if purchasing a gallon at home or abroad, expect to have less remaining after purchase.

What is a cup?

A cup is a unit of measurement equal to 8 ounces. There are 16 cups in a gallon, 8 in a half-gallon, 4 in a quart, and 2 in a pint.

Besides the US cup, there are metric and Imperial cups, units of liquid measurement.

How to measure liquid ingredients

To measure wet ingredients properly, use standard measuring cups with a pour spout on the side (aka liquid measuring cups).

Place your measuring cup on a flat surface, such as a table, and pour the liquid until you reach the desired amount.

The easy way is to bend down so that you are at eye level with the container; you will get the most precise measurement. This same method works to measure a third or a half of a cup.

Note: Dry measuring cups are different from liquid measuring cups.
