A quart (qt) is a unit of volume measurement.
A single quart is equal to 32 fluid ounces (fl oz), 2 pints, or 4 cups.
It is a key measurement in both the imperial and United States customary systems. The plural form is quarts.
The word "quart" comes from the Latin word quartus, meaning "a fourth part."
This name is a direct clue to its size: a quart is exactly one-quarter of a gallon. This simple relationship makes it an easy-to-remember unit.
It's crucial to know that the US and Imperial (UK) quarts are not the same size. While both systems are related, their definitions for a quart differ significantly.
This difference is critical to remember when converting recipes or measurements between countries.
The United States customary system also distinguishes between a liquid quart and a dry quart.
A liquid quart is used for liquids like milk or oil, while a dry quart measures the volume of dry goods like berries or flour.
They are not the same volume.
A gallon (gal) is a unit of volume, most commonly associated with the imperial and US customary systems of measurement.
It is equal to 128 Fluid Ounces (fl-oz).
A common point of confusion is the difference between the US gallon and the imperial gallon (used in the UK and other Commonwealth nations).
They are not the same size!
This difference stems from historical definitions that were standardized differently in the US and Britain during the 18th and 19th centuries.
So, if you're comparing fuel efficiency, remember that "miles per gallon" ratings are based on different-sized gallons!
The word "gallon" has a rich history, tracing its roots back through several languages.
It originates from the Old Northern French word galon, which referred to a liquid measure.
This term is believed to have originated from the Gallo-Roman word gallēta, meaning a "pail" or "bucket." The ultimate origin likely goes back to a Celtic word, highlighting the unit's long-standing use in European trade and daily life for centuries.
While we typically associate the gallon with liquids, there is also a US dry gallon.
This unit, not commonly used today, is equivalent to one-eighth of a bushel, or about 4.405 liters. It was historically used to measure dry goods such as grain or fruit.
This is also why the famous "10-gallon hat" is a misnomer; its name doesn't refer to its volume.
Instead, it is thought to originate from the Spanish word galón, meaning "braid," which refers to the braided band on the hat.
