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
