Calculated annually by EIA as the average of the thermal conversion factors for each type of crude oil imported weighted by the quantities imported.
* 1949-1993: EIA adopted the Bureau of Mines thermal conversion factor of 5.825 million Btu per barrel as reported in a Bureau of Mines internal memorandum, "Bureau of Mines Standard Average Heating Values of Various Fuels, Adopted January 3, 1950." * 1994 forward: Calculated by EIA as the annual quantity-weighted average of the conversion factors for Distillate Fuel Oil, 15 ppm Sulfur and Under (5.770 million Btu per barrel), Distillate Fuel Oil, Greater Than 15 ppm to 500 ppm Sulfur (5.817 million Btu per barrel), and Distillate Fuel Oil, Greater Than 500 ppm Sulfur (5.825 million Btu per barrel).
* 1967 forward: Calculated annually by EIA as the average of the thermal conversion factors for all hydrocarbon gas liquids consumed (see Table A1) weighted by the quantities consumed.
The dose conversion factors due to the natural radionuclide ([sup.266]Ra, [sup.232]Th and [sup.40]K) in the ground (floor) and walls were obtained by summing the products of emission probability and conversion factor for each of the [gamma]-rays energies emitted by the radionuclides concerned.
The absorbed dose rate conversion factors for an outdoor and indoor exposure in two types of Nigeria mud houses have been estimated.

The conversion factor
computations were different for the two versions.
* 1963-1979: EIA adopted the thermal conversion factor
calculated annually by the American Gas Association (AGA) and published in Gas Facts, an AGA annual publication.
