Convert erg to joule
Please provide values below to convert erg [erg] to joule [J], or Convert joule to erg.
1 erg = 1e-07 J. To convert erg to joule, multiply the value by 1e-07; to go the other way, divide by it (1 J = 10000000 erg). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 erg = 1e-07 J
- 1 J = 10000000 erg
- 10 erg = 1e-06 J
- 100 erg = 1e-05 J
How to Convert Erg to Joule
1 erg = 1e-07 J
Example: convert 15 erg to J:
15 erg = 15 × 1e-07 J = 1.5e-06 J

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.
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.
Frequently Asked Questions
What is 1 erg in joule?
1 erg (erg) = 1e-07 joule (J).
How do you convert erg to joule?
Multiply the erg value by 1e-07. For example, 25 erg × 1e-07 = 2.5e-06 J.
What is 10 erg in joule?
10 erg = 1e-06 J.
Which unit is larger, the erg or the joule?
The joule is the larger unit: 1 erg equals only 1e-07 J.
