The Joule is the unit of energy in the SI (metric) system. 1 Joule is the energy required to move 1 meter against a force of 1 Newton. (The Newton is the force that will accelerate a mass of 1 kg at a rate of 1 meter/sec2). The Kilojoule is 1000 Joules, and is equal to 0.9478 BTU. Also 1 Kilojoule = 737.6 ftlbforce, and 1 Kilojoule per second = 1.341 hp. Joules can be mechanical, electrical, or thermal in origin, and there is the mechanical equivalent of heat, 1 calorie = 4.2 joules. 1 Kilojoule per second = 1 Kilowatt.
To convert from kilo joules to joules you have divide by 1000 as 1 kilo joule is equal to 1000 joules. E.g. 2 kilo joules equals 2000 joules.
There are 56,000 joules in 56 kilojoules. This is because there are 1,000 joules in a kilojoule.
