Convert watt second to j
Watt-Second
A watt-second (symbol: W·s) is a unit of energy equal to exactly one joule, defined as the energy delivered by one watt of power sustained for one second. It is an alternative expression of the joule that makes the power-time relationship explicit, and the two are used interchangeably in physics and engineering. The watt-second is sometimes encountered in capacitor and flash photography energy specifications.
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).
