About these units
US Pint (pt)
One eighth of a US gallon, 473.176 mL (16 US fluid ounces). The US pint is about 17% smaller than the imperial pint.
Pint seems to come from Old French pinte, possibly from a Latin word meaning painted, perhaps because capacity marks were painted on containers. British North America inherited the 231-cubic-inch wine gallon around 1707, and the US liquid pint was derived from it as one eighth. After Britain adopted the imperial gallon in 1824, American and British pints parted ways for good.
Today the US liquid pint is exactly 28.875 cubic inches, or 473.176473 milliliters. The imperial pint, at 568.26125 mL, is about 20 percent larger. That is why a pint of beer in an American bar is a lesser drink than a pint in an English pub, and why recipes from different countries cannot swap pints blindly. In the US a pint is a common size for ice cream, cream and craft beer, and a separate US dry pint of about 550.6 milliliters measures blueberries and cherry tomatoes.
1 US pint = 0.473176473 liters (exactly).

Metric Teaspoon (tsp)
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).
