Energy is not Watts per hour (Watts/hour), it's Watts times hours (Watt-hours). Sorry for pedantry, but the units are the topic of discussion here.

And in turn, watts are joules per second. Resolve Hours to 3600 seconds means 1 Wh = 3600 Joules. Which is the unit we should be using.

That's got me trying to visualise "mile-gallons", and failing because its dimensions would be "length^4".

I did not imply that at all.
