How is Electricity Cost Calculated?
The cost to run an electrical appliance is calculated using the formula:
Cost = (Power in Watts × Time in Hours) / 1000 × Cost per kWh
What is a kWh?
kWh (Kilowatt-hour) is the unit of energy used for billing electricity. 1 kWh equals using 1,000 Watts of power for 1 hour. For example, running a 1,000-Watt Space Heater for 1 hour uses exactly 1 kWh.
