The answer is 0.001 kilojoules in a joule 1J = 0.001kJ
1 Kilojoule is equal to 1000 joules. So, 980 kilojoules x 1000 joules per kilojoule = 980000 joules.
A Joule is a Watt-second (or W=J/s). Therefore, 3.5 kWh = 3.5*3600 kWs = 3.5*3600*1000 W-s = 12.6 million Joules
1 kilojoule = 1,000 joules
kJ for kilojoules and J for joules.
I may be wrong, but kilo I think stands for 1000. Since a kilojoule is larger than a joule, I believe that you have to move the decimal point to the left. For example you would have less than 1 whole kilojoule in a joule, so it would be some thing like .00001 or something to that effect.
A kilojoule is about 4.2 times smaller than a calorie. Find the amount of calories you need in a day and multiply that number (e.g 2000) by 4.2.
Watt means joule/second, kW (kilowatt) means kilojoule/second, i.e., thousands of joules per second.
kilo means 1000. 1 kilojoule = 1000 joules
A 'kilojoule' is one thousand joules. This is a unit of work energy.
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 kilojoules to joules you have divide by 1000. meaning 1 kilo joule is equal to 1000 joules.
