These firewood BTU ratings charts compare the heat energy content of common firewood types along with both green and dry weight per cord. These charts were compiled from various sources so some comparisons between species may conflict some due to variables in laboratory variables of how much actual solid wood is in a cord.

A cord is 128 cubic feet but because of air space between pieces the actual amount of solid wood may be only 70-90 cubic feet. This depends on the size and shape of the pieces and how tightly they are stacked. Because of this variable consider the firewood BTU values and weight in these charts to be approximate.

The BTU in firewood is usually close to the same per pound between species. One pound of dense hardwood will have about the same amount of energy as one pound of light softwood. The difference in energy content is in the woods density. A cord of the more dense wood will have more energy than a cord of less dense softwood.
