Convert j to watt hour
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).
Watt-Hour
The watt-hour (Wh) is a unit of energy equal to 3600 joules, representing the energy expended by a device consuming one watt of power over the course of one hour. It is a subunit of the kilowatt-hour and is commonly used to specify the capacity of batteries and small electronic devices. Watt-hours provide a practical measure of electrical energy storage and consumption at the consumer scale.
