Convert from cord [firewood] to cubic yard

Unit Definition (cord [firewood])
The cord [firewood] is a traditional unit of volume used to measure stacked firewood. Like most traditional units of trade, the cord has varied somewhat according to local custom. In the United States, the cord is defined legally as the volume of a stack of firewood 4 feet wide, 8 feet long, and 4 feet high. (In Maryland, the law specifies that the wood be stacked "tight enough that a chipmunk cannot run through it." Presumably it is up to the buyer to provide the chipmunk.) One cord is a volume of 128 cubic feet, about 3.6246 cubic meters, or 3.6246 steres. The name apparently comes from an old method of measuring a stack of firewood using a cord or string.

Unit Definition (cubic yard)
The cubic yard is a traditional unit of volume in English speaking countries. One cubic yard equals 27 ft³, 46 656 in³, 0.764 555 m³, or 764.555 liters. A cubic yard holds about 201.97 U.S. liquid gallons or about 168.20 British Imperial gallons.
