how do you convert power "P" into kWh?

eg. Plasma TV power = 210W

how do i make that to find its usage in kWh assuming it was on for only on for 2 hours?

thanks.

A kilowatt = 1000 watts... so you take the number of watts and divide by 1000... now you have the number of Kilowatts/hour. So multiply the number by 2, because it was 2 hours.

EDIT: to find your charge, take the number of kilowatts and multiply it by the price of kW/h
