More wheels than sense
A kilowatt hour is energy divided by time multiplied by time. That means the time dimensions cancel and it's a unit of energy, which in most situations is expressed in Joules.
1kWh = 3.6MJ
You could do it in electron volts I suppose, I've always wanted an excuse to use the yotta prefix.
1kWh = 22.5YeV
I didn't even know there was a yotta , everyday should be a learning day cheers.
