[nb 3] The Queen Anne wine gallon of 231 cubic inches was adopted in 1707 and still serves as the definition of the US gallon. A US tun is then the volume or of a rectangular cuboid with dimensions 36 by 38.5 by 42 inches. When the imperial system was introduced the tun was redefined in the UK and colonies as 210 imperial gallons.
A butt approximately equated to 108 imperial gallons (130 US gallons; 491 litres) for ale or 126 imperial gallons (151 US gallons; 573 litres) for wine (also known as a pipe), although the Oxford English Dictionary notes that "these standards were not always precisely adhered to".
The tun (Old English: tunne, Latin: tunellus, Medieval Latin: tunna) is an English unit of liquid volume (not weight), used for measuring wine, [1] oil or honey. Typically a large vat or vessel, most often holding 252 wine gallons, but occasionally other sizes (e.g. 256, 240 and 208 gallons) were also used. [2] The modern tun is about 954 litres.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
A Fixture Unit is not a flow rate unit but a design factor. A fixture unit is equal to 1 cubic foot (0.028 m 3) of water drained in a 1 + 1 ⁄ 4 inches (32 mm) diameter pipe over one minute. [2] One cubic foot of water is roughly 7.48 US gallons (28.3 L; 6.23 imp gal). A Fixture Unit is used in plumbing design for both water supply and waste ...
Wine was shipped in barrels of 119 litres (31 US gal; 26 imp gal). A barrel of oil, defined as 42 US gallons (35 imp gal; 160 L), is still used as a measure of volume for oil, although oil is no longer shipped in barrels. The barrel has also come into use as a generic term for a wooden cask of any size.

Nominal Pipe Size is used for the outside diameter of pipes. Below NPS14, the NPS number is not consistent with the pipe diameter in inches. Copper tubing, however, is measured in nominal size, 1 ⁄ 8 inch less than the outside diameter. The Schedule system is used for standard pipe thicknesses.
