1 US liquid barrel = 119,240.4712 milliliters

How to convert US liquid barrels to milliliters

To convert US liquid barrels to milliliters, multiply the number of US liquid barrels by 119,240.4712. The factor is rounded to 10 significant digits. To go the other way, multiply milliliters by 0.000008386414361 (rounded).

milliliters = US liquid barrels × 119,240.4712

Example: 10 US liquid barrels = 1,192,404.712 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 Liquid Barrel (bbl (US))

US customaryTraditional unit (still used in some regions)

31.5 US gallons (119.24 L). The standard US barrel for liquids such as beer.

Most American fluid barrels are set at 31.5 US gallons, which works out to about 119 litres (119.24 L as used here). That is a half of the old 63 gallon wine hogshead, so the liquid barrel is a direct descendant of the English wine-gallon system rather than of any grain measure. Beer is the best known use, though the common US beer keg barrel is slightly smaller at 31 gallons, about 117 litres.

The English name came from French baril. Colonial and later American law treated the barrel as a trade unit for wine, beer, cider and spirits, but other liquids, from molasses to petroleum, were sold in containers of other sizes, so the phrase barrel never meant a single universal amount.

Confusion with its neighbours is common. It is roughly 3 percent larger than the dry barrel of 7,056 cubic inches, and well short of the 42 gallon barrel used for oil. The 63 gallon hogshead is exactly twice its size.

1 US liquid barrel = 119.2404712 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).
