Answer:
To calculate the consumption of an electrical appliance in kWh, you have to take into account three factors:
the capacity of your electrical appliance, expressed in watt.
the number of hours that the appliance is in use in one day.
the number of days per year when the appliance is in use.
The calculation is as follows:
[number of hours’ use] x [number of days’ use] x ([capacity of appliance expressed in watt] / 1,000) = number of kWh
The capacity should be divided by 1,000 to convert the number of watts into the number of kilowatts. This finally gives us the number of kWh (kilowatt hours).
