lights bulb usage

hebron

How much does it cost to leave a 60watt light on for one hour?
How do you work it out please?

Thank you.

1 unit of electricity is 1000w. This means you can use the bulb for 16.66 hours for 1 unit. The unit price is on your bill.

Thanks very much

1 unit of electricity is 1000w for 1 hour. Sorry to be pedantic, but understanding this does help to make sense of queries like the OP's

Being that you are pedantic is it 1000Kwh, 1000kWh, 1000kwh, 1000kwH, 1000 Kwh, 1000 kWh, 1000kwH, or 1000 kwh?

Lower case k for kilo. Upper Case is for Kelvin I think.

Wikipedia sheds some light on this(pun intended)

"kW·h" or "kW h"

Wrong! 1000kWh nothing else is correct.

1 unit is 1000Wh actually, or 1kWh.

I was correcting the pedants incorrect use of various combinations of upper and lower case letters, not answering the OP's question!

Why is the OP using a 60W light bulb anyway? Have they not heard of saving the planet!
