The butt is an obsolete English measure of liquid volume equalling two hogsheads, being between 450 and 1,060 litres (99 and 233 imp gal; 120 and 280 US gal) by various definitions.
[1] A butt approximately equated to 108 imperial gallons (130 US gallons; 491 litres) for ale or 105 imperial gallons (126 US gallons; 477 litres) for wine (also known as a pipe), although the Oxford English Dictionary notes that "these standards were not always precisely adhered to".
[1][2] The butt is one in a series of English wine cask units, being half of a tun.
