Facts about Teaspoon
Basic facts: Unit of volume based on an item of cutlery is known as a teaspoon [symbol: tsp]. The United States customary teaspoon is equivalent to precisely 4.928922 mL. As a unit of culinary measure, the metric teaspoon is equivalent to 5 mL. The size of teaspoons ranges from approximately 2.5 to 7.3 mL [0.088 to 0.257 imp fl oz; 0.085 to 0.247 US fl oz].
History: The teaspoon was initially widely used as a unit of apothecaries’ measure and was equivalent to 1 fluid dram [or drachm], 1/4 of a tablespoon, or 1/8 of a fluid ounce. The apothecaries’ teaspoon was officially known by the Latin “cochleare minus” [cochl. min.] in order to differentiate it from the tablespoon or “cochleare majus” [cochl. maj.]. The older definition of the teaspoon differs from the definitions of the teaspoon used nowadays; teaspoon was smaller back then. This was due to tea’s costliness in 1660s England, which resulted in smaller teacups and teaspoons. In 1710, when England began importing tea from China, it reduced the cost of tea, therefore the size of teacups and teaspoons grew, and by the 1730s, became 1/3 the size of a tablespoon. The same size ratio is used today in both the metric and US customary teaspoons [however, the actual volumes differ].
Use: The teaspoon is widely used in cooking in specific countries, as well as for measuring medical prescriptions.
Facts about Fluid Ounce
Basic facts: A fluid ounce [symbol: fl oz] is a unit of volume in the United States customary and imperial systems of measurement. The United States fluid ounce is 1/16 of a US fluid pint, 1/128 of a US liquid gallon, which is equivalent to 29.57 mL. The imperial fluid ounce is 1/20 of an imperial pint, and 1/160 of an imperial gallon, which is equivalent to 28.4 mL.
History: The fluid ounce was initially based on the volume occupied by one ounce [weight] of a given liquid like water or wine, accordingly varying based on the system being used. In 1824, the imperial gallon was represented as the volume of ten pounds of water at a temperature of 16.7°C. The definition of the imperial gallon was later changed to be equivalent to 4.54609 liters, which made the imperial fluid ounce equivalent to exactly 28.4130625 mL.
Initially, the United States fluid ounce was based on the wine gallon used in England before 1824. In 1959 after the adoption of the international inch, the U.S. fluid ounce became equivalent to exactly 29.5735295625 mL.
Use: As the name shows, the fluid ounce is generally used as a measurement of liquid volume. As one of the many measurements of volume, it is mainly used in the United States and the United Kingdom.
