Convert j to gigajoule
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).
Gigajoule
The gigajoule (GJ) is a unit of energy equal to one billion joules, or 1,000 megajoules. It is used to measure large-scale energy consumption, such as industrial energy use, natural gas billing, and the energy content of large fuel quantities. One GJ is approximately equal to 277.78 kilowatt-hours or 0.9478 million BTU.
