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.
Quite a few things have changed since the 1940s when the concept originated. After the Second World War, typically it was the housewife who cooked, cleaned, ironed, and served the family meals; kitchen sizes were generally smaller than today. The kitchen was considered a working area, and planning considered mostly utilitarian angles.
The general standard for liquids is 31.5 gal or half a hogshead. The common 55-gallon size of drum for storing and transporting various products and wastes is sometimes confused with a barrel, though it is not a standard measure. In the U.S., single servings of beverages are usually measured in fluid ounces.
A standard method for sizing tires combines millimeters for overall width and inches for the wheel diameter on which they fit. [117] In lighting, light bulbs use eighths of an inch for bulb diameter and full inches for fluorescent tube lengths, while the socket is always in millimeters (for example, the standard "medium Edison screw" is E26).

= 10 parts per million by volume = 10 ppmv = 10 volumes/10 6 volumes NO x molar mass = 46 kg/kmol = 46 g/mol Flow rate of flue gas = 20 cubic metres per minute = 20 m 3 /min The flue gas exits the furnace at 0 °C temperature and 101.325 kPa absolute pressure. The molar volume of a gas at 0 °C temperature and 101.325 kPa is 22.414 m 3 /kmol.
In the SI, the standard metre is now defined as exactly 1 ⁄ 299 792 458 of the distance that light travels in a second. [10] [11] The metre can be realised by measuring the length that a light wave travels in a given time, or equivalently by measuring the wavelength of light of a known frequency. [12]
