Gallon (gal) definition

A gallon is a unit of measure, which is used to measure volume commonly used in the USA and Britain. The gallon can be abbreviated as Gal. In comparison to the liter in the metric system, there are approximately 4.546 liters in an imperial gallon, 3.785 liters in a US liquid gallon, and 4.405 liters in a US dry gallon. In its own measurement systems, both US gallon and imperial gallon equals 4 quarts and 8 pints in their respective systems. 

Gallon (gal) history

Like other units in the US customary and imperial systems, the history of gallon as a volumic measurement unit dates back to the Medieval Ages when the gallon was used to measure wine and beer in England. The wine gallon size and the ale (beer) gallon size were different. The first one was equal to the size of a US gallon, while the second was a bit larger and equal to the size of an imperial gallon. 

Historically, the word gallon originates from the Old Norman French galon, corresponding to Old French jalon, which is related to jale (meaning bowl) in Old French.

Gallon (gal) current use

Similar to the quart, there are three types of gallons including a US liquid gallon, a US dry gallon, and an imperial gallon. The sizes of these gallons are slightly different as can be seen above. Of the three types, an imperial gallon is the largest one which is equal to 4.54609 liters (exactly) or approximately 10 pounds of pure water at 62° Fahrenheit. 

Of the two US gallons, the US liquid gallon is more commonly used to measure gasoline, water, and milk while the US dry gallon is less common. 

The gallon is commonly used in the sale of fuel for vehicles. The imperial gallon is widely used in the sale of petrol in British Overseas Territories and the countries influenced by the UK even though the UK has switched to a newer system of measurement, the SI. Gasoline sold by the US is measured in the US liquid gallon, which can be found in, certainly, the USA, and some countries in Latin America. 

Quart (qt) definition

The quart is a measurement unit of volume used in the US customary system and the British imperial system. The unit can be abbreviated as qt. A quart equals 2 pints. If you are someone from a country that adopts the metric system, a quart is equal to approximately a liter. US liquid and dry quarts are equivalent to approximately 0.95 liter and 1.1 liters respectively, and an imperial quart is 1.13 liters.

Quart (qt) history

The history of quart, a commonly used measurement unit in the USA and the UK, dates back hundreds of years to the Medieval Ages. The quart was found to be used in Geoffrey Chaucer’s Miller’s Tale (1380s - 1390s)  as a measure for ale, a type of beer. 

Etymologically, the word quart originates from the Latin word quartus, which means one-quarter.

Quart (qt) current use

The quart can be seen all over places in the USA from a quart of milk at the supermarket to a quart of whipping cream in a cooking book. 

There are three types of quart that are currently used, an Imperial quart, a US liquid quart, and a slightly larger US dry quart. As their terms imply, a liquid quart measures liquid substances like water, milk, oil, etc. while a dry quart is used to measure dry ingredients.

Relationship between gallons and quarts

Both quarts and gallons are two units of measurement in both the US customary system and the British imperial system. The quart is a smaller unit than the gallon. There are 4 quarts in a gallon, or a quart equals a quarter of a gallon, which explains its unit name, a quart. 

Both units are commonly used in the US to measure the volume of water, milk, and especially gasoline or petrol. 

Generally speaking, the relationship between quarts and gallons can be expressed as:

1 gallon = 4 quarts
