Kopna

The Kopna was a Russian measure for grain garbage. The measure was a counting and piece measure.

One Kopna had about 50 sheaves . In some areas even 60 to 100 sheaves were calculated for a Kopna. The grain threshed out of the sheaves was converted into Cheet value , a measure of volume. In winter cereals , the grain yield from 60 sheaves resulted in a Cheet value of grain, 60 Kopna also resulted in 60 Cheet value. The types of grain made a difference when measuring, which led to very inaccurate information. It should also be noted that the Cheet value was not the same in size in all regions.

At the end of the 16th century, the hay harvest in Kopna was also measured.
