The reputed quart was a measure equal to two-thirds of an imperial quart (or one-sixth of an imperial gallon), at about 0.7577 liters, which is very close to one US fifth (0.757 liters). The reputed quart was previously recognized as a standard size of wine bottle in the United Kingdom, and is only about 1% larger than the current standard wine ...

[7] [8] A US liquid gallon can contain about 3.785 kilograms or 8.34 pounds of water at 3.98 °C (39.16 °F), and is about 16.7% less than the 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.
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.
A notable outlier is the United States (US). Although used in some contexts, the US has resisted full adoption; continuing to use "a conglomeration of basically incoherent measurement systems". [2] Adopting the metric system is known as metrication.
World map, colour-coded to show the years the countries started the process of official conversion to the metric system. Using data from PhD thesis by Hector Vera and NIST. Metrication or metrification is the act or process of converting to the metric system of measurement. [ 1 ]
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide).The atoms are linked in a continuous framework of SiO 4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2.
Peak B-grades are roughly one level easier than V-grades (e.g. V8 was equivalent to B9). The V-grade / Font-grade systems (sometimes the "technical grade" component of the British E-grade system is used) have replaced Peak B-grades in Britain but they appear in some guidebooks and some boulder grade conversion tables.
