Or 16 c = 1 gal 1 gallon to cups (gal to 1c) Cups to gallon conversion 1 cup to a gallon (1c to gal) Why?īecause the US gallon is smaller than the UK one, meaning that if purchasing a gallon at home or abroad, then expect to have less remaining after purchase. It is essential to distinguish between the US customary gallons and Royal gallons. Imperial gallon (aka British or Royal gallon) is 20% more than US gallon and equals 4.546 liters. The conversion system says that a gallon equals 3.78 liters or 16 cups. US gallon is a standard unit for measuring volume in America. Interestingly, Canadians consider the debate liter and gallon as standard units. Therefore, it is about 14.1% bigger than the US fluid gallon. US dry gallon is equal to ⅛ US bushel or 4.4 L. Royal gallon is scarcely found in the United Kingdom they still use an imperial measurement system along with a metric system. You might be surprised that there are different types of gallons. Gallon (abbreviation 'gal') is a unit of volume used in the USA and some Latin American and Caribbean countries. The gallon has a fascinating history, with many different definitions and redefinitions throughout the years. So no worries next time you go shopping! This post will answer this burning question. Or, when purchasing a standard gallon of water, you need to know the number of cups of water it serves. Knowing how many cups make a gallon is essential for making sure that your homemade juice stored in a gallon plastic jug will be enough to share with guests during the next picnic. So when you look for such an essential drink dispenser sold as 1 or 2 gallons in size, your next question might be how many cups it fits. But what is a party without the perfect glass jar to serve iced tea, lemonade, or sangria? Gallon (US) to Liter Conversion Table Gallon (US) ġ5 gal (US) = 15 × 3.785411784 L, l = 56.The summertime is all about barbecues and parties. It is also used to measure certain non-liquid volumes such as the size of car trunks, backpacks and climbing packs, computer cases, microwaves, refrigerators, and recycling bins, as well as for expressing fuel volumes and prices in most countries around the world. However, due to the mass-volume relationship of water being based on a number of factors that can be cumbersome to control (temperature, pressure, purity, isotopic uniformity), as well as the discovery that the prototype of the kilogram was slightly too large (making the liter equal to 1.000028 dm 3 rather than 1 dm 3), the definition of the liter was reverted to its previous, and current definition.Ĭurrent use: The liter is used to measure many liquid volumes as well as to label containers containing said liquids. History/origin: There was a point from 1901 to 1964 when a liter was defined as the volume of one kilogram of pure water under the conditions of maximum density at atmospheric pressure. One liter is equal to 1 cubic decimeter (dm 3), 1,000 cubic centimeters (cm 3), or 1/1,000 cubic meters (m 3). Literĭefinition: A liter (symbol: L) is a unit of volume that is accepted for use with the International System of Units (SI) but is technically not an SI unit. 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). Definition: A gallon is a unit of volume specifically regarding liquid capacity in both the US customary and imperial systems of measurement.
