One quad of BTU is 1.055 etc  exajoules.
I remember cause I have written it several times.
I could not translate a cubic foot of gas to Joules.

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?
