I strongly doubt it, but it certainly varies from place to place. Where I live, PG&E (the gas supplier for most of the northern 2/3 of California) prices its gas by the "therm". A phone call revealed that a "therm" is defined as 1000 BTUs. This unit (actually determined for billing purposes by measuring the volume used and the outdoor temperature, and applying a complicated formula written by the state Public Utilities Commission) is supposed to be fairer than pricing by volume because it allows for the fact that the gas expands with temperature: one "therm" in the summer occupies a greater volume but contains the same amount of gas. Does anyone here even recall how to convert the BTU to SI?
