The quart (symbol: qt) [1] is a unit of volume equal to a quarter of a gallon. Three kinds of quarts are currently used: the liquid quart and dry quart of the US customary system and the imperial quart of the British imperial system. All are roughly equal to one liter. It is divided into two pints or (in the US) four cups. Historically, the ...

A US liquid gallon contains about 3.7854 kilograms (8.3454 lb) of water at 3.98 °C (39.16 °F), and is about five-sixths of an imperial gallon. There are four quarts in a gallon, two pints in a quart and 16 US fluid ounces in a US pint, which makes the US fluid ounce equal to 1 / 128 of a US gallon.
Scoop (utensil) sizes, numbered by scoops per quart; Thickness of leather is measured in ounces, 1 oz equals 1 ⁄ 64 inch (0.40 mm). [30] Bolts and screws follow the Unified Thread Standard rather than the ISO metric screw thread standard. Knitting needles in the United States are measured according to a non-linear unitless numerical system.
Factors in bold are exact. If exact factors have more than 7 places, they are rounded and no longer exact. This convert module replaces these rounded figures with the exact figures. For example, the NIST document has 1 square mile = 2.589 988 E+06 square meters. The convert template has 1 square mile = 2,589,988.110336 square meters.
One litre is about 5.6% larger than a US liquid quart, and about 12% smaller than an imperial quart. A mnemonic for its volume relative to an imperial pint is "a litre of water's a pint and three-quarters"; this is very close, as a litre is exactly 800000 ⁄ 454609 imperial pints. A cubic foot has an exact volume of 28.316846592 litres.
Britain's North American colonies adopted the British wine gallon, defined in 1707 as exactly 231 cubic inches (3 in × 7 in × 11 in) as their basic liquid measure, from which the US wet pint is derived, and the British corn gallon (1 ⁄ 8 of a standard "Winchester" bushel of corn, or exactly 268.8025 cubic inches) as its dry measure, from ...
It is therefore not possible to make an exact conversion between these units. Representative figures for the amount of grapes needed for 100 L of wine are 160 kg for white wine, 130 kg for red wine, and 140 kg for a mixture of red and white wine. [1] Thus: [2] for white wine, 100 hl/ha ≈ 16,000 kg/ha (16 t/ha) = 6.5 tons per acre.
