US Pints to Milliliters (pt to mL)

1 US pint equals 473.176473 milliliters exactly.

1 US pint = 473.176473 milliliters

How to convert US pints to milliliters

To convert US pints to milliliters, multiply the number of US pints by 473.176473. This factor is exact. To go the other way, multiply milliliters by 0.002113376419 (rounded).

milliliters = US pints × 473.176473

Example: 10 US pints = 4,731.76473 milliliters.

Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.

About these units

US Pint (pt)

US customaryCurrent unit

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).

Milliliter (mL)

Metric (SI)Current unit

One thousandth of a liter, or exactly 1 cubic centimeter. Used for medicine, cooking and small containers.

Milliliters inherit everything from the liter, since the prefix simply means one thousandth. Because the liter is a cubic decimeter, a milliliter works out to exactly one cubic centimeter, a coincidence the metric system built in on purpose so that volume, length and mass interlock. One milliliter of water has a mass of about one gram, so a dosing syringe, a kitchen scale and a measuring jug can all be checked against one another.

Today milliliters dominate wherever small amounts must be measured precisely: medicine, flavorings, perfume, shampoo and the fine print on drink labels. Spelling is a mild regional split, with uppercase mL preferred in the United States, Canada and Australia and lowercase ml common in the UK and Europe. For scale, a US teaspoon is just under 5 mL, a US tablespoon is about 14.8 mL, and the US nutrition-label cup is exactly 240 mL, so one such cup is 240 of these tiny units.

1 milliliter = 0.001 liters (exactly).
