Convert joule to erg
Please provide values below to convert joule [J] to erg [erg], or Convert erg to joule.
1 J = 10000000 erg. To convert joule to erg, multiply the value by 10000000; to go the other way, divide by it (1 erg = 1e-07 J). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 J = 10000000 erg
- 1 erg = 1e-07 J
- 10 J = 100000000 erg
- 100 J = 1000000000 erg
How to Convert Joule to Erg
1 J = 10000000 erg
Example: convert 15 J to erg:
15 J = 15 × 10000000 erg = 150000000 erg

Joule
The joule (J) is the SI unit of energy, work, and heat, defined as the work done when a force of one newton acts over a distance of one meter.
History/Origin
The joule was named after James Prescott Joule in 1889 to honor his work in energy and thermodynamics. It was adopted as the SI unit of energy in 1948.
Current Use
The joule is widely used in physics, engineering, and everyday contexts to quantify energy, work, and heat in various applications, including electricity, mechanics, and thermodynamics.
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.
