However, most gas property tables use units of absolute pressure; to convert a gauge pressure to absolute pressure the prevailing atmospheric pressure must be added to the gauge pressure.

Therefore, conversion factors for gas volumes used above do not corresponded to those used for ordinary volumes.2.A decatherm （also spelled dekatherm） is technically a unit of energy, not volume. One decatherm is approximately 1000000 BTU. However

20、 the decatherm is sometimes used to express natural gas volumes based on its heating value, for this table a heating value of 1000 BTU/scf was used.GAS HEATING VALUEMJ/m3 （mega Joule per cubic meter）26.704BTU/scf （British Thermal Unit per standard cubic foot）1/26.704=0.03744The standard gas referenc
