About these units

Metric Teaspoon (tsp)

Cooking & barCurrent unit

Exactly 5 mL, used in most countries.

Five milliliters is the metric teaspoon, a figure so tidy that it has become the working definition for medicine and food labels. The traditional British teaspoon was an imperial fluid drachm, one eighth of an imperial fluid ounce, about 3.55 milliliters, and the American one was 4.93 mL. US nutrition labeling law now defines a teaspoon as exactly 5 milliliters.

The 5 mL teaspoon matters most when dosing medicine. Kitchen spoons vary widely, with one Greek survey of 71 household teaspoons finding volumes from 2.5 to 7.3 mL, so measuring spoons, syringes and calibrated cups are the safer tools. It also anchors the metric cooking system: three teaspoons make a 15 mL tablespoon, and fifty fit in a 250 mL metric cup. Australia keeps a 5 mL teaspoon but counts four of them in its larger 20 mL tablespoon.

1 metric teaspoon = 0.005 liters (exactly).

Imperial Pint (pt (UK))

Imperial (British)Current unit

Exactly 568.26125 mL (20 imperial fluid ounces). The pint of beer and milk in the UK and Ireland.

The imperial pint derives from Parliament's 1824 decision to replace Britain's assorted gallons with one defined by ten pounds of water at 62 degrees Fahrenheit. A pint is one eighth of that gallon and holds 20 imperial fluid ounces, or exactly 568.26125 milliliters. The word reached English from French pinte, which in modern French now means half a liter, while Canadian French uses it for the imperial quart.

That pint is about 20 percent larger than the US liquid pint of 473 mL, so a pint in Dublin or London buys noticeably more beer than one in Chicago. When Britain metricated, the pint was kept for draught beer and cider and for milk in returnable bottles, and draught beer has to be served in measured, stamped glasses. Culturally the pint is more than a measure: it is shorthand for a night at the pub.

1 imperial pint = 0.56826125 liters (exactly).
