1 US peck = 8,809.767542 milliliters

How to convert US pecks to milliliters

To convert US pecks to milliliters, multiply the number of US pecks by 8,809.767542. The factor is rounded to 10 significant digits. To go the other way, multiply milliliters by 0.000113510373 (rounded).

milliliters = US pecks × 8,809.767542

Example: 10 US pecks = 88,097.67542 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 Peck (pk)

US customaryTraditional unit (still used in some regions)

One quarter of a US bushel (8.81 L), a traditional measure for apples and other produce.

Anyone who has recited the tongue twister about Peter Piper has met the peck, a dry measure of a quarter bushel. The American version is about 8.81 L, or 8 dry quarts, and the imperial peck set after 1824 is larger at about 9.09 L. Scotland had its own pecks before that act, roughly 9 L for wheat, peas, beans and meal and about 13 L for barley, oats and malt, with four pecks making a firlot.

In Britain the peck is obsolete apart from the rhyme and a few older Bible translations, where it appears in Matthew 5:15. In the United States it lingers in grocery stores and farm stands, where apples and some other produce are still sold by the peck. NIST gives the US peck as 8.809768 L.

1 US peck = 8.809767542 liters (approximately).

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).
