How to Convert Joules to Ergs
Basic Conversion Formula
Practical Example
Given:
- Energy = 5 joules
Solution:
E = 5 J × 107 = 5 × 107 erg
Explanation of Terms
- E (Ergs): The unit of energy in the CGS (centimeter-gram-second) system. One erg is defined as the energy transferred when a force of one dyne is applied over a distance of one centimeter.
- J (Joules): The unit of energy in the SI (International System of Units). One joule is the energy transferred when one newton of force is applied over a distance of one meter.

FAQs
What is an Erg?
An Erg (erg) is a smaller unit of energy, commonly used in fields like physics and astronomy. It is defined as the amount of energy transferred when a force of one dyne moves an object one centimeter.
1 erg = 10⁻⁷ Joules (J).
How do I convert Joules to Ergs?
To convert Joules to Ergs, multiply the energy in Joules by 10⁷.
Formula: erg = J × 10⁷
What is the relationship between Joules and Ergs?
1 Joule is equal to 10⁷ Ergs, making the Erg a much smaller unit of energy than the Joule.
Why do we use Ergs instead of Joules in some cases?
Ergs are often used in specific scientific contexts, such as astrophysics or other fields involving small amounts of energy. The smaller unit is convenient when dealing with small energy values.
