What is a Kilowatt Hour? The unit symbol for a watt is “W” and the unit symbol for a kilowatt is “kW”. A kilowatt hour is the amount of energy you get from one kilowatt for one hour. Electricity use over time is measured in kilowatt hours. Your electric company measures how much electricity you use in kilowatt hours, abbreviated “kWh”. An example of what one kilowatt-hour can do is: 1200 electric shaves, dry your hair 15 times, 4 TV evenings, use a small refrigerator for 24 hours or 4 evenings of light with 60W incandescent lamps.

What is kilowatt-hour (kWh)? One kilowatt-hour is defined as the energy consumed by power consumption of 1kW during 1 hour: 1 kWh = 1kW ⋅ 1h. One kilowatt-hour is equal to 3.6⋅106 joules: 1 kWh = 3.6⋅106 J. The energy E in kilowatt-hour (kWh) is equal to the power P in kilowatts (kW), times the time t in hours (h).

Calculating the Kilowatt Hours Your Solar Panels Produce (Solar Panel Output) How Much Power Am I Using? A kilowatt-hour is a basic unit of energy, which is equal to power (1000 watts) times time (hour). Your electric bills show how the average number of kWh you use per month. For example, a 50 Watt light bulb left on for one hour would be 50 Watt hours, and 20 50 watt light bulbs running for one hour would be 1 kilowatt-hour (kWh).
