At last! Someone using a rational energy unit.

In fact, the BTU is one of the best of the British (actually now just
American) units. It's 1055 Joules, but as a rule of thumb you can think
of it as a kJ.

But having different units for every single energy source is just nuts.

Who else uses the therm, roughly .1 GJ, but the . Gas industry?

lists natural gas prices in MMBtu, where MM=1000*1000
or one million. That's pretty nice, just about the same thing as a GJ,
so we and the Canucks can actually think we are talking the same language.

[And MMBtu ~= MCF, so we have a three-way match]
