![]() This same definition was used for the imperial quart up until 1824 when the UK re-defined the imperial gallon.Ĭurrent use: The respective versions of the quart are used mainly in the United States and the United Kingdom, though in the UK, the use of the liter is now mandated as a result of metrication. The current definition of the US quart is based on the English wine gallon. History/origin: The quart is based on the gallon, the definition of which has changed throughout history based on the commodity being referenced. In both the UK and the US, the quart is equal to ¼ of its respective gallon. In the UK, the imperial quart is equal to 1.136523. ![]() In the US, a liquid quart is equal to approximately 0.946353 liters and a dry quart is equal to approximately 1.101221 liters. Improve your math knowledge with free questions in Which unit of volume is appropriate: ounces, cups, pints, quarts, or gallons and thousands of other. Quartĭefinition: The quart (symbol: qt) is a unit of volume in the United States customary and imperial systems of measurement. The imperial gallon is used even more sparingly than the US gallon, with most countries around the world using liters when referencing fuel. Gallons are also widely used in fuel economy expression in the US, as well as some of its territories. History/origin: The term gallon most closely originates from "galon" in Old Northern French and developed as a system for measuring wine and beer in England, resulting in measures such as the wine gallon, ale gallon, and imperial gallon.Ĭurrent use: In the United States (US), gallons are often used for larger containers, such as half gallon tubs of ice cream or one-gallon cartons of milk. A US fluid ounce is therefore 1/128 of a US gallon while an imperial fluid ounce is 1/160 of an imperial gallon. Further differentiating the US and the imperial gallon, a US gill is divided into four fluid ounces, while an imperial gallon is divided into five. A cup is comprised of two gills, making one gallon equal four quarts, eight pints, sixteen cups, or thirty-two gills. Quarts are then divided into two pints and pints are divided into two cups. In both systems, the gallon is divided into four quarts. In contrast, the imperial gallon, which is used in the United Kingdom, Canada, and some Caribbean nations, is defined as 4.54609 liters. The US gallon is defined as 231 cubic inches (3.785 liters). The answer is 4 quarts is equal to 128 fluid ounces.Definition: A gallon is a unit of volume specifically regarding liquid capacity in both the US customary and imperial systems of measurement. Multiply when converting a larger unit to a smaller unit, quarts to ounces.įinally, multiply the number of quarts by 32. The answer is 32 fluid ounces is equal to 4(1/2) cups.įirst, figure out if you need to multiply or divide. Then, check the table for the unit equivalence.įinally, divide the number of ounces by 8. Divide when converting a smaller unit to a larger unit, fluid ounces to cups. Some handy kitchen knowledge 8 fluid ounces (fl oz) 1 cup 1 pint (pt) 2 cups 1 quart (qt) 2 pints 4 cups 1 quart 1 gallon (gal) 4 quarts. Use the information in the table to convert customary units of capacity.įirst, figure out if you need to multiply or divide. Between quarts and pints, the basic relationship is 1 qt = 2 pt. For example, the basic relationship between cups and fluid ounces is 1 cup = 8 fl oz. To use the table, match up one of the red numbers with the units you are changing to. Here is a table that shows equivalent customary units of capacity. To convert different units of capacity, you need to know how much of one unit is equal to another unit. These types of conversions are often necessary when doing an activity involving liquids, like cooking. Once again, it’s time to show you how you can do these conversions yourself. Abbreviated: 4 cups in 1 qt So you can measure out 4 cups of an ingredient and it will be the same amount as 1 qt. You may have to figure out how many cups are in a pint or how many quarts are in a gallon. How Many Cups in a Quart There are 4 cups in 1 quart. Here are the common units of capacity from smallest to largest. There are several customary units of capacity. Identifying Equal Customary Units of CapacityĬapacity is the volume or the amount of liquid an item can hold.
