The US fluid ounce is based on the US gallon, which in turn is based on the wine gallon of 231 cubic inches that was used in the United Kingdom prior to 1824. With the adoption of the international inch, the US fluid ounce became 1⁄128 gal × 231 in 3 /gal × (2.54 cm/in) 3 = 29.5735295625 mL exactly, or about 4% larger than the imperial unit.
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, [citation needed] but in the US it is defined as 1 ⁄ 128 of a US gallon. Consequently, a fluid ounce of water weighs ...
In Canada, a teaspoon is historically 1⁄6 imperial fluid ounce (4.74 mL) and a tablespoon is 1⁄2 imperial fl oz (14.21 mL). In both Britain and Canada, cooking utensils come in 5 mL for teaspoons and 15 mL for tablespoons, hence why it is labelled as that on the chart. The volumetric measures here are for comparison only.
Dram (unit) The dram (alternative British spelling drachm; apothecary symbol ʒ or ℨ; [a] abbreviated dr) [4] [5] : C-6–C-7 [6] is a unit of mass in the avoirdupois system, and both a unit of mass and a unit of volume in the apothecaries' system. [5] It was originally both a coin and a weight in ancient Greece. [7]
The units of cubic length (the cubic inch, cubic foot, cubic mile, etc.) are the same in the imperial and US customary systems, but they differ in their specific units of volume (the bushel, gallon, fluid ounce, etc.). The US customary system has one set of units for fluids and another set for dry goods. The imperial system has only one set ...
Some countries choose to base the definition on mass of alcohol (in grams) while others base the unit on the volume (in ml or other volume units). For comparison, both measurements are shown here, as well as the number of standard drinks contained in 500 millilitres (16.9 US fluid ounces) of 5% ABV beer (a typical large size of beer in Europe ...
Apothecaries' system. The apothecaries' system, or apothecaries' weights and measures, is a historical system of mass and volume units that were used by physicians and apothecaries for medical prescriptions and also sometimes by scientists. [1] [2] [3] The English version of the system is closely related to the English troy system of weights ...
The ounce ( / ˈaʊns /) is any of several different units of mass, weight, or volume and is derived almost unchanged from the uncia, an Ancient Roman unit of measurement . The avoirdupois ounce (exactly 28.349523125 g) is 1⁄16 avoirdupois pound; this is the United States customary and British imperial ounce.
