How many milliliters in a half a teaspoon

Please provide values below to convert teaspoon (US) to milliliter [mL], or vice versa.

Teaspoon

Definition: A teaspoon (symbol: tsp) is a unit of volume based on an item of cutlery. The United States customary teaspoon is equal to exactly 4.928922 mL. The metric teaspoon is equal to 5 mL.

History/origin: The teaspoon was originally used as a unit of Apothecaries' measure and was equal to 1 fluid dram, ¼ of a tablespoon, or 1/8 of a fluid ounce. This definition of the teaspoon is smaller than the definitions of the teaspoon used today. This is partially due to tea being expensive in 1660s England, resulting in smaller teacups and teaspoons. Once England began importing tea from China in 1710, reducing the cost of tea, the size of teacups and teaspoons increased, and by the 1730s, became 1/3, rather than 1/4 the size of a tablespoon. This is the same size ratio in use today in both the US customary and metric teaspoons (though the actual volumes differ).

Current use: The teaspoon is widely used in cooking within certain countries, as well as for measuring pharmaceutic prescriptions. Outside of these applications, the unit is not particularly used, with measurements such as the liter or cubic meter being preferred.

Milliliter

Definition: A milliliter (symbol: mL) is a unit of volume that is accepted for use in the international system of units (SI). One milliliter is equal to 1 cubic centimeter (cm3), 1/1,000,000 cubic meters (m3), or 1/1000 liters.

History/Origin: The base unit of the milliliter is the liter (US spelling), spelled "litre" in SI terms. The term "litre" was originally part of the French metric system and was derived from the term "litron," one of the older versions of the French litre. Refer to the liter page for further details.

Current use: Milliliters are used to measure the volume of many types of smaller containers in everyday use, such as plastic bottles, cans, drinking, glasses, juice and milk cartons, yogurt, toothpaste tubes, perfume/cologne bottles, etc. Many measurement devices such as graduated cylinders, beakers, pipettes, measurement cups, etc. also use the measurement of milliliters.
