This calculator is designed to provide approximate weights for many different wood varieties, but seasoned with the expected and logical caveats. Wood varies considerably in weight based on numerous factors, including area, climatic conditions, cutting time, age and many more condition.

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 thick and 8 feet long. (A cord has about 85 cu ft of wood and not 128, because of the air spaces between the pieces).

The fact that their average density is usually lower than hardwoods means that you get less weight of wood in a cord and the extra 5% of volatile fuel will not make up for this.

If all negotiations for buying and selling wood are on a cord basis, there should be no confusion. Occasionally, firewood is sold on a weight basis, and this can be especially confusing because the weight of wood varies greatly depending upon the moisture content.

Green wood contains up to 50 percent of its weight in water. The first stage of combustion involves bringing this mass of water up to its vaporization point. The energy expended in doing this does ... Assuming 90 cubic feet of solid wood per cord (and remembering that an actual 128 cubic foot cord has lots of air space in it),

To conclude the g/hr- and g/kg-curve analysis, the increase in g/kg emissions at burn rates above 4.0 kg/hr is due to decreasing combustion efficiency which is caused, in most cases, by excess combustion-air cooling or by dilution of the combustion gases given off by the heated wood before they can burn.
