[nb 1] (This was the basis for calling 64 gallons a quarter.) At some time before the 15th century, it was reduced to 252 gallons, so as to be evenly divisible by other small integers, including seven. [nb 2] Note that a 252-gallon tun of wine has a mass of approximately 2060 pounds, [6] between a short ton (2000 pounds) and a long ton (2240 ...
In the standard system the conversion is that 1 gallon = 231 cubic inches and 1 inch = 2.54 cm, which makes a gallon = 3785.411784 millilitres exactly. For nutritional labeling on food packages in the US, the teaspoon is defined as exactly 5 ml, [22] giving 1 gallon = 3840 ml exactly. This chart uses the former.
The table of imperial avoirdupois mass is the same as the United States table up to one pound, but above that point, the tables differ. The imperial system has a hundredweight, defined as eight stone of 14 lb each, or 112 lb ( 50.802 345 44 kg ), whereas a US hundredweight is 100 lb ( 45.359 237 kg ).
The Imperial gallon was defined with yet another set of temperature and pressure values (62 °F (17 °C) and 30.0 inHg (102 kPa)). To convert a number of wine gallons to the equivalent number of Imperial gallons, multiply by 0.833111. To convert a number of Imperial gallons to the equivalent number of wine gallons, multiply by 1.200320.
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 ] Equivalents
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. The word tun is etymologically related to the word ton for the unit of mass, the mass of a tun of wine being approximately one long ton , which is 2 240 pounds ...
In atmospheric chemistry, mixing ratio usually refers to the mole ratio r i, which is defined as the amount of a constituent n i divided by the total amount of all other constituents in a mixture: r i = n i n t o t − n i {\displaystyle r_{i}={\frac {n_{i}}{n_{\mathrm {tot} }-n_{i}}}}
