Here are two charts showing the weight and available heat content of one cord of firewood of various species, the first sorted by heat value, and the second sorted alphabetically for easy lookup. The heat value measurement used is the British Thermal Unit, or BTU, which is defined as the amount of thermal energy it takes to raise one pound of water one degree F. One MBTU = one million BTUs.

Weight and Heat content figures are based on seasoned wood at 20% moisture content, and 85 cu ft of wood per cord. A cord of wood is defined as a stack 4 feet high, 4 feet deep and 8 feet long, which comes to 128 cu ft, but we deduct for air space between the pieces in the stack.

* Compressed sawdust logs sell by weight, not volume. BTU content given is for one ton (2,000 lbs)
