A full bushel is represented by a basket in the lower right. A bushel (abbreviation: bsh. or bu.) is an imperial and US customary unit of volume based upon an earlier measure of dry capacity. The old bushel is equal to 2 kennings (obsolete), 4 pecks, or 8 dry gallons, and was used mostly for agricultural products, such as wheat. In modern usage ...
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.
In agricultural practice, a bushel is a fixed volume of 2,150.42 cubic inches (35.2391 liters). The mass of grain will therefore vary according to density. Some nominal weight examples are: [26] [27] 1 bushel (corn) = 56 lb (25.4012 kg) 1 bushel (wheat) = 60 lb (27.2155 kg) 1 bushel (barley) = 48 lb (21.7724 kg)
Indeed, the bushel, the best-known unit of dry measure because it is the quoted unit in commodity markets, is in fact a unit of mass in those contexts. Conversely, the ton used in specifying tonnage and in freight calculations is often a volume measurement rather than a mass measurement.
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
{{convert|100|kg|lb}} → 100 kilograms (220 lb) {{convert|100|lb|kg}} → 100 pounds (45 kg) The unit-codes should be treated as case-sensitive: {{convert|100|Mm|mm}} → 100 megametres (1.0 × 10 11 mm) The output of {{convert}} can display multiple converted units, if further unit-codes are specified after the second unnamed parameter ...
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). In both systems, 20 hundredweights make a ton.
A coomb was 16 stone (100 kg) for barley and 18 stone (110 kg) for wheat. The US grain markets quote prices as cents per bushel , and a US bushel of grain is about 61 lb (28 kg), which would approximately correspond to the 4-bushel coomb (4 × 61 lb = 244 lb ≈ 111 kg).
