British Thermal Unit Conversion Factors
 (0.1 MB)
Factors used to estimate gross (or higher or upper) heat content in British thermal units (Btu) of a given amount of energy measured in physical units, such as barrels. Includes approximate heat content of petroleum, biofuels, natural gas, coal, coal coke, and electricity. Also includes heat rates for electricity net generation.
