Ok, light bulbs I get come in 20 or 40 or 60 watts. But if there was a 1,000 watt light bulb and it was left on for 1 hour would it use a kilowatt-hour? Also correct me if I’m wrong; kilowatt is 1,000 watts, megawatt is 1,000,000 watts, and a gigawatt is a billion watts. If both the things I’ve said are true then would a 1,000,000 watt light bulb left on for an hour use a megawatt-hour? Any other information you think I should know about this would be appreciated.

Yes that is correct.
Remember that watt is a unit of power, or energy used over time while kilowatt hour or megawatt hour is a unit of energy since the power is multiplied by the time.

You answered your own questions, but you did that so beautifully and accurately.
Remember: Kilo is 1000; Mega: 1000 of 1000 and Giga: 1000 of Mega.
Any appliance that uses for one hour of a watt of - kilo, or a mega or a Giga - will use kilo watt hour, mega watt hour, giga watt hour. Simple. Actually I am repeating what you said earlier but said it in a different way so that you can remember it easily. No more confusion, arrrrrrighta?
Looks like you are smart but not sure of something you already know.

Yes, that is exactly that.
You do have electrical appliances that use over a 1000 watt: hair dryer are 1000 to 1500 watt, for instance.

That's the idea, and the mega watt light would try to use a meq of power but would cause a large blackout in your area.
