Convert kilojoule to erg
Please provide values below to convert kilojoule [kJ] to erg [erg], or Convert erg to kilojoule.
1 kJ = 10000000000 erg. To convert kilojoule to erg, multiply the value by 10000000000; to go the other way, divide by it (1 erg = 1.0000e-10 kJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kJ = 10000000000 erg
- 1 erg = 1.0000e-10 kJ
- 10 kJ = 100000000000 erg
- 100 kJ = 1e+12 erg
How to Convert Kilojoule to Erg
1 kJ = 10000000000 erg
Example: convert 15 kJ to erg:
15 kJ = 15 × 10000000000 erg = 150000000000 erg

Kilojoule
A kilojoule (kJ) is a unit of energy equal to 1,000 joules, used to quantify energy transfer or work done.
History/Origin
The kilojoule was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring energy, especially in fields like nutrition and physics, replacing the joule for larger quantities.
Current Use
The kilojoule is widely used in nutrition to express food energy content, in physics and engineering to measure energy transfer, and in various scientific and industrial applications within the 'Energy' converter category.
Erg
The erg is a unit of energy in the centimeter-gram-second (CGS) system, defined as the amount of work done when a force of one dyne displaces an object by one centimeter.
History/Origin
The erg was introduced in the late 19th century as part of the CGS system of units, primarily used in physics to measure small amounts of energy before the adoption of the SI system.
Current Use
Today, the erg is largely obsolete and rarely used outside of specific scientific contexts, with the SI unit joule being the standard for energy measurement. It remains relevant in some fields like astrophysics and theoretical physics.
Frequently Asked Questions
What is 1 kilojoule in erg?
1 kilojoule (kJ) = 10000000000 erg (erg).
How do you convert kilojoule to erg?
