Convert erg to gigajoule
Please provide values below to convert erg [erg] to gigajoule [GJ], or Convert gigajoule to erg.
1 erg = 1.0000e-16 GJ. To convert erg to gigajoule, multiply the value by 1.0000e-16; to go the other way, divide by it (1 GJ = 1.0000e+16 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 = 1.0000e-16 GJ
- 1 GJ = 1.0000e+16 erg
- 10 erg = 1.0000e-15 GJ
- 100 erg = 1.0000e-14 GJ
How to Convert Erg to Gigajoule
1 erg = 1e-16 GJ
Example: convert 15 erg to GJ:
15 erg = 15 × 1e-16 GJ = 1.5e-15 GJ

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.
Gigajoule
A gigajoule (GJ) is a unit of energy equal to one billion joules, used to measure large amounts of energy such as in power generation and fuel consumption.
History/Origin
The gigajoule was introduced as part of the International System of Units (SI) to provide a standard measure for large-scale energy quantities, especially in scientific and industrial contexts, gaining prominence in the 20th century.
Current Use
Gigajoules are commonly used today to quantify energy in fields like energy production, consumption, and engineering, particularly for large-scale systems such as power plants, fuel storage, and energy audits.
Frequently Asked Questions
What is 1 erg in gigajoule?
1 erg (erg) = 1.0000e-16 gigajoule (GJ).
How do you convert erg to gigajoule?
Multiply the erg value by 1.0000e-16. For example, 25 erg × 1.0000e-16 = 2.5000e-15 GJ.
What is 10 erg in gigajoule?
10 erg = 1.0000e-15 GJ.
Which unit is larger, the erg or the gigajoule?
The gigajoule is the larger unit: 1 erg equals only 1.0000e-16 GJ.
