How many kilowatt-hours does a oven use per hour?

Answer 1

Watts does not have a time component to it; so you should have asked, "How many kilowatt-hours does an oven use per hour?'

For example, if the oven uses 1600 watts, then in one hour, it would use 1600 watt-hours, or 1.6 kilowatt-hours.

Answer 2

The energy consumption of an oven can vary depending on the model and temperature setting, but a typical oven uses around 2-2.5 kilowatt-hours per hour of operation.
