How the formula works
Both attojoule and erg measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attojoules by 1.000000000e-11 to get ergs. To reverse the conversion, multiply a erg value by 100000000000 to get back to attojoules.
Frequently asked questions
What is Attojoule (aJ)?
A attojoule (aJ) is a metric-prefixed unit of energy equal to 10-18 joules, a fraction of a single joule, using the SI atto 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 attojoules to ergs?
Multiply the attojoule value by 1.000000000e-11 to get the equivalent in ergs. For example, 5 aJ × 1.000000000e-11 = 5.000000e-11 erg.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-11 is an exact, non-rounded value.
Can I convert ergs back to attojoules?
Yes. Divide the erg value by 1.000000000e-11, or multiply it by 100000000000, to get attojoules.
