About these units

US Fluid Ounce (fl oz)

US customaryCurrent unit

One 128th of a US gallon, 29.5735 mL. Not the same as the weight ounce, and about 4% larger than the imperial fluid ounce.

Fluid ounce began as an attempt to link volume to weight: the volume occupied by one ounce of some substance, such as wine in England or water in Scotland. Definitions varied by region and by liquid. When Britain defined its imperial gallon in 1824 as the space of ten pounds of water, the imperial fluid ounce came out so that an ounce of water weighs about one avoirdupois ounce. The US fluid ounce followed a different path and comes from the older wine gallon.

The US fluid ounce is exactly 1/128 of a US gallon, 29.5735295625 milliliters, about 4 percent bigger than the imperial one at 28.4130625 milliliters. American nutrition labels use yet another figure, treating one fluid ounce as 30 milliliters, a convenient rounding for serving sizes. The name is a trap, because a fluid ounce measures space while a weight ounce measures mass. A US fluid ounce of water weighs a bit more than an ounce of weight, while a fluid ounce of honey weighs considerably more.

1 US fluid ounce = 0.02957352956 liters (approximately).

Centiliter (cL)

Metric (SI)Current unit

One hundredth of a liter (10 mL). Used on drink labels across Europe.

Centi- means one hundredth, so a centiliter is 0.01 liter, which is 10 milliliters or 10 cubic centimeters. Among the liter's smaller multiples it is the one that suits glassware: it indicates the capacity of drinking glasses and small bottles, and shot-sized servings of alcohol are often 3 cL.

The unit sits between the milliliter, used for medicine and small packaging, and the deciliter, which is ten times larger at 10 cL. The figure used here is exactly 0.01 liter. Because 1 cL is 10 cubic centimeters, a 33 cL container holds 330 mL, and three such measures of 3 cL come to 9 cL. Ten centiliters make one deciliter.

1 centiliter = 0.01 liters (exactly).
