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 Milliliter

Basic facts: A milliliter is a measurement used in the metric system. A symbol of it is [mL]. This volume unit is accepted for use in the international system of units [SI]. In other words, a milliliter is a metric unit employed to measure capacity (capacity is the amount of liquid a container can hold: one liter contains 1,000 milliliters, so to convert liters to milliliters you multiply the number of liters times 1,000) that is equal to one-thousandth of a liter. 1 milliliter equals to 1 cubic centimeter [cm3], 1/1000 liters or 1/1,000,000 cubic meters [m3]. So, this unit of capacity is equivalent to 0.033815 fluid ounces, or 0.061025 cubic inches. 

History: The liter (US spelling), spelled “litre” in SI terms is the base unit of the milliliter. The term “litre” was initially part of the French metric system and originated from the term “litron,” one of the older interpretations of the French litre. Take a look at the liter page for additional details.

Use: Milliliters are used to measure the volume of many kinds of smaller containers in day-to-day use, like plastic bottles, drinking glasses, cans, juice and milk cartons, yogurt, perfume/cologne bottles, toothpaste tubes, etc. Multiple measurement devices like beakers, graduated cylinders, measurement cups, pipettes, etc. also use the measurement of milliliters.
