Convert kilowatt hour to j

Kilowatt-Hour

The kilowatt-hour (kWh) is a unit of energy equal to 3.6 × 10⁶ joules (3.6 MJ), representing the energy consumed by a device operating at one kilowatt of power for one hour. It is the standard unit of electrical energy used by utilities worldwide for billing residential and commercial electricity consumption. Despite not being an SI unit, it is accepted for use with the SI and is ubiquitous in everyday energy measurement.

Joule

The joule (/dʒaʊ,dʒuːljawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
