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.
Ammonium bifluoride is a component of some etchants. It attacks silica component of glass: SiO 2 + 4 [NH4] [HF2] → SiF 4 + 4 [NH 4 ]F + 2 H 2 O. Potassium bifluoride is a related more commonly used etchant. Ammonium bifluoride has been considered as an intermediate in the production of hydrofluoric acid from hexafluorosilicic acid.
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 ...
A sample nutrition facts label, with instructions from the U.S. Food and Drug Administration [1] The nutrition facts label (also known as the nutrition information panel, and other slight variations) is a label required on most packaged food in many countries, showing what nutrients and other ingredients (to limit and get enough of) are in the food.

Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property ...
236.588 mL. The cup is a cooking measure of volume, commonly associated with cooking and serving sizes. In the US, it is traditionally equal to one-half US pint (236.6 ml). Because actual drinking cups may differ greatly from the size of this unit, standard measuring cups may be used, with a metric cup being 250 millilitres .
