What is the difference between KW and KWh?

462 views

Update: I am actually searching for really simple, intuitive ways to explain it. I have a background in engineering, but am struggling to explain why we “pay for kwh”, and not kw (on our electricity bill) to someone who doesn’t. I have tried in many ways but maybe I’m not giving the right examples or making the right comparisons. I am really searchig for a way to ELI5.

Turn your heater on? It’s drawing 1kW = 1000 watts.

Turn it off after a second? Zero watts now in use.

Turn it on for an hour? You’ve used 1kWh of power.
