1Qts

1Qts is an informal textual shorthand used to denote one quart, a unit of volume in both the US customary and British imperial systems. While not a formal symbol, the abbreviation can appear on recipes, product labels, or data fields where quantities are abbreviated. The exact meaning of 1Qts depends on the measurement system being used.

In the United States, a US liquid quart equals 32 US fluid ounces, equals one quarter of a US gallon, and is approximately 0.94635 liters. It is also equivalent to two pints or four cups. This makes 1 quart a common reference point in cooking, beverage, and household measurements.

In the British Imperial system, an imperial quart equals 40 imperial fluid ounces, equals one quarter of an imperial gallon, and is about 1.13652 liters. The imperial quart is slightly larger than the US quart because the underlying gallon and fluid ounce sizes differ between systems.

Usage note: because 1Qts can be ambiguous when the system is not specified, it is advisable to spell out “one quart” or use “qt” and indicate the system (US or imperial) to avoid confusion, especially in recipes, shipping, or technical specifications.

Etymology: the term quart derives from the Latin quartus meaning “one quarter,” reflecting its historical role as a quarter of a gallon in various measurement systems. See also quart, US customary units, and Imperial units.
