WebIn the United States, heating value is expressed as British thermal units (Btus) per pound or per gallon at 60°F. The SI metric units are joules per kilogram or per cubic meter at 15°C. For gross (or higher) heating value, the water produced by the combustion is assumed to be recondensed to liquid. WebOne pound of oven-dry wood of any hardwood species has an available heat value of about 8,600 Btu. Resinous softwood species, such as shortleaf pine, tend to average slightly higher at 9,050 Btu per oven-dry pound. Freshly cut Missouri hardwoods commonly have a 75 percent moisture content on an oven-dry basis.
