Convert erg to microjoule
Please provide values below to convert erg [erg] to microjoule [µJ], or Convert microjoule to erg.
1 erg = 0.1 µJ. To convert erg to microjoule, multiply the value by 0.1; to go the other way, divide by it (1 µJ = 10 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 = 0.1 µJ
- 1 µJ = 10 erg
- 10 erg = 1 µJ
- 100 erg = 10 µJ
How to Convert Erg to Microjoule
1 erg = 0.1 µJ
Example: convert 15 erg to µJ:
15 erg = 15 × 0.1 µJ = 1.5 µJ

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.
Microjoule
A microjoule (µJ) is a unit of energy equal to one millionth of a joule, used to measure small amounts of energy.
History/Origin
The microjoule was introduced as part of the metric system to facilitate the measurement of very small energy quantities, especially in scientific and engineering contexts, with the adoption of the International System of Units (SI).
Current Use
Microjoules are commonly used in fields such as electronics, physics, and biology to quantify small energy transfers, signals, or reactions, often in research and technical applications.
Frequently Asked Questions
What is 1 erg in microjoule?
1 erg (erg) = 0.1 microjoule (µJ).
How do you convert erg to microjoule?
Multiply the erg value by 0.1. For example, 25 erg × 0.1 = 2.5 µJ.
What is 10 erg in microjoule?
10 erg = 1 µJ.
Which unit is larger, the erg or the microjoule?
The microjoule is the larger unit: 1 erg equals only 0.1 µJ.
