How is electricity measured in units?

A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWh) of electricity.

What is unit used to measure energy?

The basic unit of energy. A joule is defined as the amount of energy expended by a force of one newton moving an object one meter in the same direction as the force. Kilowatts-hours measure the total amount of electricity used over time.

How is electricity consumption measured at home?

A device using 100 watts over 10 hours would utilize 1kWh of energy (100×10=1,000=1kW). The Wikipedia example: a 40-watt bulb, used for 25 hours (40×25=1,000 watts = 1 kW) would also be using 1 kWh (even though it took 25 hours to get there). The kWh is how most home energy costs are calculated.
