* In the UK, teaspoons and tablespoons are formally 1 / 160 and 1 / 40 of an imperial pint (3·55 mL and 14·21 mL), respectively. 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).

A firkin is a unit of volume or mass used in several situations. Its etymology is likely to be from the Middle English ferdekyn, probably from the Middle Dutch diminutive of vierde 'fourth' (a firkin originally contained a quarter of a barrel). Firkin also describes a small wooden cask or tub for butter, lard, liquids, or fish. [1] [2]

See Weight for detail of mass/weight distinction and conversion. Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.
This improper name persists, especially in elementary textbooks. In biology, the unit "%" is sometimes (incorrectly) used to denote mass concentration, also called mass/volume percentage. A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as "1%" or "1% m/v" (mass/volume). This is incorrect because ...
For example, in a recipe that calls for 10 pounds of flour and 5 pounds of water, the corresponding baker's percentages are 100% for the flour and 50% for the water. Because these percentages are stated with respect to the weight of flour rather than with respect to the weight of all ingredients, the sum of these percentages always exceeds 100%.
1% m/v solutions are sometimes thought of as being gram/100 mL but this detracts from the fact that % m/v is g/mL; 1 g of water has a volume of approximately 1 mL (at standard temperature and pressure) and the mass concentration is said to be 100%. To make 10 mL of an aqueous 1% cholate solution, 0.1 grams of cholate are dissolved in 10 mL of ...
