what is kwh A kilowatt hour unit symbol kW h or kW h commonly written as kWh is a non SI unit of energy equal to 3 6 megajoules MJ in SI units which is the energy delivered by one kilowatt of power for one hour Kilowatt hours are a common billing unit for electrical energy supplied by electric utilities
A kilowatt is 1 000 watts For example a 1 000 watt vacuum cleaner is also a 1 kW vacuum cleaner kWh stands for kilowatt hour kWh it s the way we measure energy in the home 1 kilowatt hour is the amount of energy it takes to run a 1 000 watt or 1kWh appliance for 1 hour A kilowatt hour kWh is a unit of energy that represents the consumption of one kilowatt kW of power over a duration of one hour In simpler terms if you were to run an appliance that requires one kilowatt of power continuously for one hour it would use one kilowatt hour of energy

While Energy measured in Wh or kWh represents the quantity of electricity that has been consumed or produced over a certain period of time Power measured in W or kW represents the rate at which Updated 05 04 2023 A kilowatt hour is a unit of energy used to measure energy consumption or generation Electricity providers use kWh to determine how much electricity you consume If you ve ever looked at or compared electricity rates you will see that these rates are priced per kWh
Kilo means 1 000 and watt is a rate of power named after the engineer called James Watt To be precise a Watt means one Joule per second and a kilowatt hour equals 3 6 megajoules What is a Joule A Joule is The kWh is a unit of measurement used to account for electricity consumption over a period of time The kWh measures energy consumption in kilowatt hours 1 watt is equivalent to consuming 1 joule for 1 second Therefore 1 kW represents the consumption of 1 000 Joules for 1 second
