How the formula works
Both decajoule and erg measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decajoules by 100000000 to get ergs. To reverse the conversion, multiply a erg value by 1.000000000e-08 to get back to decajoules.
Frequently asked questions
What is Decajoule (daJ)?
A decajoule (daJ) is a metric-prefixed unit of energy equal to 101 joules, using the SI deca prefix.
What is Erg (erg)?
An erg is the CGS (centimeter-gram-second) unit of energy, equal to one ten-millionth of a joule.
How do I convert decajoules to ergs?
Multiply the decajoule value by 100000000 to get the equivalent in ergs. For example, 5 daJ × 100000000 = 5.000000e+08 erg.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 100000000 is an exact, non-rounded value.
Can I convert ergs back to decajoules?
Yes. Divide the erg value by 100000000, or multiply it by 1.000000000e-08, to get decajoules.
