• Watthour (3,600 J)

  The watt hour (symbol Wh) is a unit of energy equal to 3.6 kilojoules. If energy is transmitted or used at a constant rate (power) over a period of time, the total energy in watt hours is equal to the power in watts multiplied by the time in hours. The kilowatt hour is commonly used as a billing unit for energy delivered to consumers by electric utilities.

• Joule (1 J)

  The joule (/dʒuːl/; 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 its 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).
