Web1 Watt is equal to 1 joule per second. So a chocolate bar might have 800,000 joules of energy in it (roughly 200,000 calories). If you use this energy at a rate of 1 watt, it'll take you 800,000 seconds to use it all up, because 1 watt = 1 joule per second. Joule (and calories) are units of energy while Watt is a unit of power. WebJoules (J) to volts (V) calculator. Enter the energy in joules, charge in coulombs and press the Calculate button: Volts to joules calculator Joules to volts calculation The voltage V in …
