What does the slash mean Ross?
I put the kil-o-watt meter on the bigger set today and in one hour, since every scene changed the " watt/hour " usage, that set averaged 286 watts for that hour but I would bet the next hour to be a different watt hour usage.
Personally, I'm looking for a tv that would use that 286 watt month.
Let me try to explain it this way.
Watts is like volume of water.
If I told you that a pump can move 100 gallons, you'll look at me like I'm an idiot.
Even a tiny little oilpump from a chainsaw will move 100 gallons. Eventually.
To get an idea of how much water a pump is actually MOVING, you say x many gallons per hour, or per minute.
If I told you this pump can move 1000 gallons a SECOND, you can imagine it's a pretty serious pump.
If I told you that pump would take 3 days to move a gallon, you know it's pretty tiny!
If I told I mixed 1000 gallons of epoxy you'd think that was a LOT.
If I told you I had 10 gallons of toothpaste, you'd think that was a LOT.
If I told you I have a dam that holds 10 gallons, you'd think I was nuts - decent bucket will hold that!
So it is with watts.
If I told you I have a solar array that'll make 10 watts, you just know it's small.
If I told you I have a light globe that takes 25 watts, you know it's a modest lamp.
If I told you my TV takes 1000 watts you're going to wonder how huge it is, because that's a LOT for a TV!
Watt-hours is simply the product (multiplication) of the units of instantaneous watts, times the time expressed in hours. Something taking 1000 watts for 6 minutes (6 minutes = 0.1 hours) is 1000 * 0.1 = 100 watt-hours.
That same load (floodlight? toaster?) running for half an hour will take 1000 * 0.5 = 500 watt-hours.
My use of a slash wasn't meant as a division sign, merely to separate the "watts" part from the "hours" part.
Some people write it as watthours, some as "watt/hours", some as "watt-hours" and others as "watt hours".
Which you use is probably less important than the fact that you indicate some time-unit where it's relevant.
