I don't get watt-hours. What's wrong with Joules? Or kJ? Why have two units for energy?
Two? I wish. You forgot eV and probably a couple of others I can't think of right now. I think it was Feynmann who said "For those who want proof that physicists are human, it is in the idiocy of all the different units which they use for measuring energy."
