US Gallons to Hectoliters (gal to hL)
1 US gallon equals 0.03785411784 hectoliters exactly.
How to convert US gallons to hectoliters
To convert US gallons to hectoliters, multiply the number of US gallons by 0.03785411784. This factor is exact. To go the other way, multiply hectoliters by 26.41720524 (rounded).
hectoliters = US gallons × 0.03785411784
Example: 10 US gallons = 0.3785411784 hectoliters.
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 Gallon (gal)
Exactly 231 cubic inches or 3.785411784 liters (128 US fluid ounces). About 17% smaller than the imperial gallon.
The US gallon is a survivor of English wine trade. Around 1706, a statute in Queen Anne's reign fixed the wine gallon at exactly 231 cubic inches, settling confusion among the competing gallons for wine, ale and corn. British colonies in North America used that wine gallon, and in 1824 Britain replaced all its gallons with a new imperial one while the United States kept the old measure. It was adopted as the legal US standard in 1836 and is still defined as exactly 231 cubic inches, or 3.785411784 liters.
That makes the US gallon about 17 percent smaller than the imperial gallon, a difference that explains why American and British fuel-economy figures cannot be compared directly. Everyday uses are milk jugs, paint cans and gasoline pumps. One gallon divides evenly into four quarts, eight pints, sixteen cups and 128 fluid ounces. A gallon of water weighs a little over 8 pounds, an easy figure to remember when loading a car with water jugs.
1 US gallon = 3.785411784 liters (exactly).

Hectoliter (hL)
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).
