Maybe this is a dumb question, but I am trying to get my units straight.
I have an electrical system which has its consumption metered every hour, so I need units that are graduated in hours.
So, given SI units, should I base it in "Joule hours" which would be Watts * 3600?
In other words, let's say I have a 100 Watt light bulb and it runs for 3 hours. Then energy consumption would be 100 * 3600 * 3 = 1,080,000 Joule-hours. Is that right?
