 From: liter To: teaspoon (US)

### Liter

Definition: A liter (symbol: L) is a unit of volume that is accepted for use with the International System of Units (SI) but is technically not an SI unit. One liter is equal to 1 cubic decimeter (dm3), 1,000 cubic centimeters (cm3), or 1/1,000 cubic meters (m3).

History/origin: There was a point from 1901 to 1964 when a liter was defined as the volume of one kilogram of pure water under the conditions of maximum density at atmospheric pressure. However, due to the mass-volume relationship of water being based on a number of factors that can be cumbersome to control (temperature, pressure, purity, isotopic uniformity), as well as the discovery that the prototype of the kilogram was slightly too large (making the liter equal to 1.000028 dm3 rather than 1 dm3), the definition of the liter was reverted to its previous, and current definition.

Current use: The liter is used to measure many liquid volumes as well as to label containers containing said liquids. It is also used to measure certain non-liquid volumes such as the size of car trunks, backpacks and climbing packs, computer cases, microwaves, refrigerators, and recycling bins, as well as for expressing fuel volumes and prices in most countries around the world.

### 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.
