How to Convert Ergs to Kilojoules
The erg and kilojoule are both units of energy. By definition, 1 kilojoule equals exactly 10000000000 ergs. This means to convert ergs to kilojoules, you divide by 10000000000.
Formula
Step-by-Step Example
Convert 5 erg to kilojoules:
We need to convert ergs to kilojoules
Since 1 kJ = 10000000000 erg, divide by 10000000000
5 ÷ 10000000000 = 5e-10
5 erg = 5e-10 kJ

About These Units
Erg (erg)
An erg is the CGS (centimeter-gram-second) unit of energy equal to 10⁻⁷ joules or 1 dyne-centimeter. Ergs appear in older scientific literature and some astronomical calculations. One joule equals 10 million ergs. Rarely used in modern applications.
Kilojoule (kJ)
A kilojoule (kJ) equals 1,000 joules or approximately 239 calories. Kilojoules measure food energy on nutrition labels in Australia, Europe, and many countries. An average adult needs 8,400-10,000 kJ daily. One kJ equals approximately 0.239 kcal.
