What is a gallon?

A gallon is a volume unit of measurement used in the Imperial and US customary systems. This unit of volume has changed throughout time, taking on different values before reaching the standards we use today.

During the 18th century in England, the gallon was a volume unit used for measuring wine and beer. The wine gallon was equivalent to the present US gallon, and the beer gallon was closer to the Imperial gallon.

The current US gallon and Imperial gallon values are:

1 US liquid gallon=3.8 Liters1 Imperial gallon=4.55 Liters\small \begin{aligned} 1 \ \text{US liquid gallon} &= 3.8\ \text{Liters} \\ 1 \ \text{Imperial gallon} &= 4.55\ \text{Liters} \end{aligned}

From here we can see that the US gallon is around one-fifth smaller than the Imperial gallon. The US liquid gallons are the ones used in the gallons to quarts converter.

What is a quart?

The quart is another volume unit that has been used throughout history. It was initially used to measure dry and liquid volumes during the medieval period, with values ranging from 0.95 to 1.16 liters, similar to their modern equivalents.

Three types of quarts are still used today:

  • The US liquid quart:
    1 US liquid quart = 0.95 Liters = 1/4 US gal

  • The US dry quart:
    1 US dry quart = 1.10 Liters = 0.29 US gal

  • The Imperial quart:
    1 Imperial quart = 1.14 Liters = 0.30 US gal

The gallons to quarts converter uses the US liquid quart.
