grain required to fill level full a Winchester bushel measure of 
2150.42 cubic inches capacity. The legal bushel is based on weight 
instead of measure or volume. For each of several grains a fixed 
number of pounds is considered a legal bushel ; for example, for wheat 
60 pounds constitutes a legal bushel; corn, rye, and flaxseed, 56 
pounds ; barley 48 pounds ; and oats 32 pounds. 
The standard Winchester bushel measure contains 32 quarts, 
whereas the actual volume in quarts of a legal bushel of grain de-

pends upon its test weight. This is illustrated in figure 2. The 
volume in quarts required for a legal bushel by weight may be de- 
termined by multiplying the legal weight per bushel by 32 and divid- 
ing that product by the test weight per bushel of the grain in ques- 
tion. For example, the legal weight of wheat being 60 pounds for 
a bushel and the test weight of the wheat in question being 50 pounds, 
how many quarts will be required to weigh 60 pounds? Solution: 
Multiply 60 by 32 and divide by 50, as follows: 60X32 = 1920-^50— 
38.4 quarts, the volume required to weigh 60 pounds or a legal bushel
