bushel 11
It is an English measure used for the grain trade. Currently almost in disuse due to its complexity of conversions and the differences that are among those used in the United States, Britain and other English-speaking countries, and even more by differences of measures from one grain to another. By way of example in United States a bushel of oats is 32 pounds and 34 Canada; for the 34, 48 normal barley malted barley, maize 56 and 60 soy and wheat. In Great Britain are: 25 pounds for corn and 27 for wheat and soy. It is taken more as a measure of mass and what if they are in agreement is that a bushel equals 8 gallons (but for each gallon or jar is of different size, here is the complexity). Even the English used a bushel, as equivalent to fanegada (surface measure). By this and many other reasons it is more better to use the metric system.
