Quarts to Gallons Converter
Definition of Quarts and Gallons
The American customary system of measurement employs the quart and the gallon as volume units.
What is Quart?
In the US customary system, one quart is the standard unit for measuring volume. It is the same as 32 ounces, or a quarter of a gallon. “qt” is the acronym for “quart.”
The Roman word “quartus,” meaning “one-fourth,” is where we get the word “quart.” In the 14th century, the quart was established as one-fourth of a gallon in England. This definition was adopted into the US customary system, making the quart an official US unit of measurement.
Milk, oil, and water are just a few of the many liquids typically measured in quarts. They are also a standard unit of measurement in the kitchen, the bakery, and for filling up automobiles, boats, and planes.
Dry quarts and liquid quarts are two different kinds of quarts. The volume of liquids is measured in quarts, but the volume of dry products such as grains, beans, or flour is measured in dry quarts.
A quart of liquid measures precisely 32 ounces, or four cups’ worth. Two dry pints, or 67.2 cubic inches, make up one dry quart.
The volume of a quart can be changed to that of a liter, a cup, or a gallon. One gallon is equivalent to four quarts, and a cup has 8 fluid ounces, as was said before. The volume of one liter is roughly 1.06 quarts.
What are Gallons
In the US customary system, a gallon is a unit of volume measurement. Four quarts is the same as eight pints, and 128 ounces is the same as four quarts. One gallon is shortened to “gal.”
The word “gallon” originally referred to a unit of liquid measurement in Old Northern French. In the 13th century, it was established in England as a standard measure for alcoholic beverages. Following this definition, the gallon was formally recognized as a unit of measurement in the US customary system.
Large quantities of liquids like gasoline, water, or chemicals are typically measured in gallons. In the United States, vehicles’ fuel economy is measured in miles per gallon (mpg), and gasoline is marketed in gallons. When determining how much pesticide or fertilizer to use, farmers typically use gallons as the unit of measurement.
The US liquid gallon and the US dry gallon are the two units of measurement used in the United States. US dry gallons are used to measure the volume of dry items like grains or fruits, while US liquid gallons are used to measure the volume of liquids.
There are 3.785 liters in a US liquid gallon and 4.405 liters in a US dry gallon.
The volume measured in gallons can be changed to that of a quart, pint, or liter. One gallon is equal to four quarts or eight pints, as was said before. The volume of one liter is about a quarter of a gallon.

Historical Context of the Quart and Gallon
There is a deep and convoluted history behind the quart and gallon. In the 14th century, the quart was established as one-fourth of a gallon in England. The Roman word “quartus,” meaning “one-fourth,” is where we get the word “quart.”
But, the gallon has been around for a lot longer. Its origins may be traced back to ancient Rome when it was initially employed to measure the volume of a cylinder with a diameter that is the same as its height. Yet, the current gallon may trace its roots back to medieval England, where the amount of ten pounds of water at a given temperature was established as the standard.
