I did a physics degree and am comfortable with Joules, but in the context of electricity bills, kWh makes more sense.
All appliances are advertised in terms of their Watt power draw, so estimating their daily impact on my bill is as simple as multiplying their kW draw by the number of hours in a day I expect to run the thing (multiplied by the cost per kWh by the utility company of course).
Do you regularly divide/multiply by 3600? That’s not something I typically do in my head, and there’s no reason to do it when everything is denominated in watts. What exactly is the benefit?
I pay my electric bill by the kWh too, and I don’t live in the US. When it comes to household and EV energy consumption, kWh is the unit of choice.
1J is 3600Wh.
No, if you’re going to lecture people on this, at least be right about facts. 1W is 1J/s. So multiply by an hour and you get 1Wh = 3600J
That’s literraly the same thing,
It’s not literally the same thing. The two units are linearly proportional to each other, but they’re not the same. If they were the same, then this discussion would be rather silly.
but the name is less confusing because people tend to confuse W and Wh
Finally, something I can agree with. But that’s only because physics is so undervalued in most educational systems.
