You can measure electricity in watts, amps, volts, and ohms. Each of these units of measurement relate to a specific aspect of electricity. (See Electric Terms). Electric use is measured in watt-hours, kilowatt-hours, and megawatt-hours. It calculated using the following formula: Energy = Power x Time. In other words, you can measure electricity by multiplying the amount of required watts by the number of watt-hours used. Letâs consider a 200-watt incandescent light bulb. In an average month, letâs suppose youâll use the light bulb for 300 hours.
