Butts (pipe) to US Gallons (butt to gal)
1 butt (pipe) equals 126 US gallons exactly.
How to convert butts (pipe) to US gallons
To convert butts (pipe) to US gallons, multiply the number of butts (pipe) by 126. This factor is exact. To go the other way, multiply US gallons by 0.007936507937 (rounded).
US gallons = butts (pipe) × 126
Example: 10 butts (pipe) = 1,260 US gallons.
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
Butt (pipe) (butt)
126 US gallons (477 L), also called a pipe: half a tun.
Butt is an obsolete English liquid measure equal to two hogsheads, and for wine it is also called a pipe. At 126 US wine gallons, or 105 imperial gallons, it holds about 477 litres (476.96 L as used here). It is half a tun, so two butts fill the largest standard cask.
The size was never fully fixed. Depending on the definition a butt ranged from about 450 to 1,060 litres, and an ale butt of roughly 108 imperial gallons (about 491 litres) differed from the wine butt. The Oxford English Dictionary is cited as warning that these standards were not always followed precisely.
The informal word buttload, meaning a large quantity, is one proposed descendant of the measure. A 1695 gauging manual by James Lightbody lists beer and ale vessels by name and content.
1 butt (pipe) = 476.9618848 liters (approximately).

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).
