How many kWh is used in one hour?
It is left running for approximately one hour. That’s one kilowatt of energy used in an hour, which is equal to 1 kWh.

How is a kilowatt equal to a Watt?
A kilowatt, or kW, is equal to a thousand watts. So the number of kW is the amount of power an electrical device uses in order to run, and a kilowatt-hour (kWh) is the amount of energy that an appliance uses every hour. For example, if your electric radiator is rated at 3 kW and is left on for an hour, it would use 3 kWh of electricity.
How do you calculate the kWh of an appliance?
If you want to know how to calculate kWh usage, you can usually find the electricity rating of an appliance either in the instructions, on the manufacturer’s website, or on a label attached to the product. This figure will be the power consumption of the appliance. If you multiply this figure in kW by the number of hours it is on, you get the kWh.
