1 hectoliter equals 3,381.40227 US fluid ounces (rounded).

1 hectoliter = 3,381.40227 US fluid ounces

How to convert hectoliters to US fluid ounces

To convert hectoliters to US fluid ounces, multiply the number of hectoliters by 3,381.40227. The factor is rounded to 10 significant digits. To go the other way, multiply US fluid ounces by 0.0002957352956 (rounded).

US fluid ounces = hectoliters × 3,381.40227

Example: 10 hectoliters = 33,814.0227 US fluid ounces.

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

Hectoliter (hL)

Metric (SI)Current unit

100 liters. Used for wine, beer and milk production and for fishing quotas.

Large producers rarely count in single liters, so the hectoliter, 100 liters or 100 cubic decimeters, is the usual unit for beverage production and export figures. Milk, beer and wine statistics are quoted in it, and so are fishing catches and quotas. Since a cubic meter holds 1,000 liters, ten hectoliters make one cubic meter, and a hectoliter is one tenth of that larger SI volume.

Hecto- is the metric prefix for one hundred, giving the symbol hL. The unit is a practical middle step between the liter on a shop shelf and the cubic meter, and it avoids long strings of digits when production totals run to many thousands of liters. The figure used here is exactly 100 liters.

1 hectoliter = 100 liters (exactly).

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).
