There are 1000 joules in a kilojoule

1 Kilojoule = 1000 Joules

1 kilojoule has 1 000 joules

1 Kilojoule is equal to 1000 joules. So, 980 kilojoules x 1000 joules per kilojoule = 980000 joules.

1000 joules = 1 kJ

A megajoule is bigger than a kilojoule because there is one million joules in a megajoule and only one thousand joules in a kilojoule.

1000 Joules = 1 kiloJoule. So divide Joules by 1000 to get kJ.

1 kilojoule = 1,000 joules

kJ for kilojoules and J for joules.

Watt means joule/second, kW (kilowatt) means kilojoule/second, i.e., thousands of joules per second.

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.

kilo means 1000. 1 kilojoule = 1000 joules

A 'kilojoule' is one thousand joules. This is a unit of work energy.

You can't convert from Joules to Watts because Joules is a measure of total energy, and Watts measure energy per second.

Kilojoule. In general, you can add "kilo" (meaning 1000) in front of any unit.

One billon. 1 joule X 1000 = 1 kilojoule = 1000 J 1 kilojoule x 1000 = 1 megajoule = 1000000 J 1 megajoule X 1000 = 1 gigajoule = 1000000000J

a kilojoule isa 1000 joules and a joule is a unit that measures the amount of force transferred from one object to another eg. the impact of an airsoft bb is measured in joules

One kilojoule equals 0.2388459 kilocalorie.

A kilojoule is 1000 Joules. The Joule is the fundamental SI unit of energy. The simplest definition in mechanical terms is that it is the work done in moving 1 meter against a force of 1 Newton. If you want it in ft lb units, 1 Joule = 0.7376 ft lbf. In electrical energy terms, 1 Watt = 1 Joule per second. In thermal energy terms, 1 calorie = 4.2 Joules, or you can express it as 1 kilojoule = 0.9478 BTU

Well since Joule is the standard unit a Megajoule (1 million joules) or a kilojoule (1000 joules) can be used. Also a kilowatt-hour (3.6 million joules) is used by electric companies to keep track of the energy people use.

Joules (J) . . . . but a Joule is quite a small amount of energy, so kilojoule is more common (kJ).

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.

They are all measurements in the Unit of the Joule. The prefix Kilo means 1000, and the prefix Mega means 1,000,000. So one KiloJoule is 1000 Joules, and one MegaJoule is 1,000,000 Joules. The only difference is QUANTITY.

By "kilo" if you mean kilocalorie: 1000 calories = 1 kilocalorie But if you mean kilojoule: 1 food calorie = 4184 joules = 4.184 kilojoules Hope this helps.

kilowatt is a measurement of power; kilojoule is a measurement of energy 1 kW = 1 kJ/second
