A teaspoon as a volume measuring unit is widely used in cooking, pharmaceutical medicine, and some other areas. A teaspoon is a very convenient unit of volume used since the middle of the 17th century. It is roughly equal to 1/3rd of a tablespoon, 1/48th of a US cup, 1/3rd of a cubic inch, or 5 mL. This unit can be abbreviated to tsp.
