WebA gigajoule is a unit of energy in the International System of Units. The symbol for gigajoule is GJ. The base unit for a gigajoule is joule and the prefix is giga. The prefix giga is derived from the Greek γίγας meaning giant and is symbolized as G. Giga denotes a factor of a billion which means that there are 1,000,000,000 joules in a gigajoule. WebJul 20, 1998 · joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of …

WebMar 28, 2012 · For now. Power = rate of doing work Watts or kiloWatts (1000 Watts = 1 kW.) Energy or work done is measured in Joules. 1000 Joules = 1 kiloJoule = 1 kJ. In one hour at one Watt we use 1 W x 3600 s = 3600 Joule = 3.6 kJ. Battery energy = Volts_average x Amp hours capacity = Watt hour capacity. 1 joule is equal to (approximately unless otherwise stated): 107 erg (exactly) 6.241 509 74 × 1018 eV 0.2390 cal (gram calories) 2.390 × 10−4 kcal (food calories) 9.4782 × 10−4 BTU 0.7376 ft⋅lb (foot-pound) 23.7 ft⋅pdl (foot-poundal) 2.7778 × 10−7 kW⋅h (kilowatt-hour) 2.7778 × 10−4 W⋅h (watt-hour) 9.8692 × 10−3 latm … See more The joule is the unit of energy in the International System of Units (SI). It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force applied. It is … See more One joule represents (approximately): • The amount of electricity required to run a 1 W device for 1 s. • The energy required to accelerate a 1 See more 1 joule is equal to (approximately unless otherwise stated): • 10 erg (exactly) • 6.24150974×10 eV • 0.2390 cal (gram calories) • 2.390×10 kcal (food calories) See more In terms of SI base units and in terms of SI derived units with special names, the joule is defined as One joule can also be defined by any of the following: See more The cgs system had been declared official in 1881, at the first International Electrical Congress.
