How the formula works
Both erg and decijoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in ergs by 0.000001 to get decijoules. To reverse the conversion, multiply a decijoule value by 1000000 to get back to ergs.
Frequently asked questions
What is Erg (erg)?
An erg is the CGS (centimeter-gram-second) unit of energy, equal to one ten-millionth of a joule.
What is Decijoule (dJ)?
A decijoule (dJ) is a metric-prefixed unit of energy equal to 10-1 joules, a fraction of a single joule, using the SI deci prefix.
How do I convert ergs to decijoules?
Multiply the erg value by 0.000001 to get the equivalent in decijoules. For example, 5 erg × 0.000001 = 0.000005 dJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 0.000001 is an exact, non-rounded value.
Can I convert decijoules back to ergs?
Yes. Divide the decijoule value by 0.000001, or multiply it by 1000000, to get ergs.
