A gigajoule (GJ) is an SI-derived energy unit equal to one billion joules, commonly used to measure large amounts of thermal, mechanical, or chemical energy.

How is kilowatt-second related to other energy units?

One kilowatt-second (kW*s) equals one kilojoule (kJ), which is 1000 joules, representing energy delivered at one kilowatt for one second.

Why convert from gigajoules to kilowatt-seconds?

Converting from gigajoules to kilowatt-seconds helps bridge large total energy quantities with energy measured for short durations or pulse events in engineering and physics.
