So that it's noted, a coulomb is a large number (some 6.24 x 10^18) of electrons. One coulomb passing through one volt of electrical potential is a joule. A joule is a (small) unit of work. One joule per second is a watt. One thousand joules per second is a kilowatt. One thousand joules per second for an hour (3600 seconds) is a kilowatt hour, which is equivalent to 3.6 megajoules. It is a shame that KW and KWH are so similar sounding and in writing, but a KW is a thousand joules

*per second*and a KHW is 3.6 megajoules (

*regardless of time*).

What does it take to get this right? Am I just too pedantic?
