Kilowatt-hours and joules are both units used to measure energy. Keep reading to learn more about each unit of measure. A kilowatt-hour is a measure of electrical energy equal to one kilowatt , or 1, watts , of power over a one hour period. Kilowatt-hours are a measure of electrical work performed over a period of time, and are often used as a way of measuring energy usage by electric companies.
The abbreviation kW h is also sometimes used. The joule is the energy equal to the force on an object of one newton at a distance of one meter. One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt.
In addition, one joule is also equal to the one watt-second. The joule is the SI derived unit for energy in the metric system. Example: An industrial fryer transforms an energy of Joule every 60 seconds, how much power in kW the fryer has.
A gold mine transforms Joule in just 60 seconds, how many kW does the mine have? A compactor transforms the energy of Joules in Seconds, what will be the power in kW of the compactor?. An industry transforms an energy of joules, in 30 seconds, how much will be the power in kW consumed by the industrial process?.
Note: In the previous conversions a time of 60 seconds is taken into account. For different variables, the calculator that appears at the beginning must be used.
