# Convert Cubic Foot to Teaspoon (US)

Please provide values below to convert cubic foot [ft^3] to teaspoon (US), or *vice versa*.

### Cubic foot

**Definition:** A cubic foot (symbol: ft^{3}) is a unit of volume in the Imperial and United States customary systems of measurement defined as the volume of a cube with side measurements of 1 ft × 1 ft × 1 ft. It is equal to 1,728 cubic inches, approximately 0.028317 cubic meters, and 28.317 liters.

**History/origin:** The cubic foot is derived from the foot, the definition of which is based on the international yard which was adopted in the 1950s and 1960s as exactly equal to 0.9144 m.

**Current use:** The cubic foot is used in the United States and in some parts of Canada and the United Kingdom, though in all of these countries, the SI (International System of Units) units of volume, liter, milliliter, and cubic meter, are also used.

### 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.
