In Canada, a "shot" may refer to an official "standard drink" of 1.5 imperial fluid ounces or 42.6 millilitres, [11] though all establishments serve a "standard drink" of 1 oz. [12] However, shot glasses available in Canada typically are manufactured according to US fluid ounces rather than imperial, [13] making them about 4% larger. Channel ...
Until 1982, STP was defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 101.325 kPa (1 atm). Since 1982, STP is defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 100 kPa (1 bar). Conversions between each volume flow metric are calculated using the following formulas: Prior to 1982,
It was supposed to be replaced by the 500 mL "half-liter", which was dropped in 1989, but is sometimes used for craft beer and malt liquor. Fifth (US) 25.6 US fl oz: 26.66 imp oz. 757 mL: A fifth (1 ⁄ 5, or 0.2) of a US gallon. Called a "Commercial Quart" because it was equivalent to 0.8 US fluid quarts. Replaced by the 750 mL "metric quart".
An imperial fluid ounce is defined in British law as exactly 28.4130625 millilitres, [15] while a US customary fluid ounce is exactly 29.5735295625 mL, [16] and a US food labelling fluid ounce is 30 mL. [17] The fluid ounce is sometimes referred to simply as an "ounce" in contexts where its use is implicit, such as bartending.
* For many years, the US standard (non-metric) wine and liquor bottle was the "fifth", meaning one-fifth of a US gallon, or 25.6 US fluid ounces (757 mL; 26.6 imp fl oz).
The teaspoon, tablespoon, and cup are defined in terms of a fluid ounce as 1 ⁄ 6, 1 ⁄ 2, and 8 fluid ounces respectively. The fluid ounce derives its name originally from being the volume of one ounce avoirdupois of water, [21] but in the US it is defined as 1 ⁄ 128 of a US gallon. Consequently, a fluid ounce of water weighs about 1.041 ...
The effect of pressure and temperature on the densities of liquids and solids is small. The compressibility for a typical liquid or solid is 10 −6 bar −1 (1 bar = 0.1 MPa) and a typical thermal expansivity is 10 −5 K −1. This roughly translates into needing around ten thousand times atmospheric pressure to reduce the volume of a ...
An imperial fluid ounce is 1 ⁄ 20 of an imperial pint, 1 ⁄ 160 of an imperial gallon or exactly 28.4130625 mL. A US customary fluid ounce is 1 ⁄ 16 of a US liquid pint and 1 ⁄ 128 of a US liquid gallon or exactly 29.5735295625 mL, making it about 4.08% larger than the imperial fluid ounce. A US food labeling fluid ounce is exactly 30 mL.
