Convert megajoule to erg
Please provide values below to convert megajoule [MJ] to erg [erg], or Convert erg to megajoule.
1 MJ = 1.0000e+13 erg. To convert megajoule to erg, multiply the value by 1.0000e+13; to go the other way, divide by it (1 erg = 1.0000e-13 MJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 MJ = 1.0000e+13 erg
- 1 erg = 1.0000e-13 MJ
- 10 MJ = 1.0000e+14 erg
- 100 MJ = 1.0000e+15 erg
How to Convert Megajoule to Erg
1 MJ = 10000000000000 erg
Example: convert 15 MJ to erg:
15 MJ = 15 × 10000000000000 erg = 150000000000000 erg

Megajoule
A megajoule (MJ) is a unit of energy equal to one million joules.
History/Origin
The megajoule was introduced as part of the metric system to measure large amounts of energy, especially in scientific and engineering contexts, aligning with the SI units established in the 20th century.
Current Use
The megajoule is used in fields such as physics, engineering, and energy industries to quantify large energy quantities, including in energy production, consumption, and scientific research.
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.
