How the formula works
Both yottajoule and erg measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in yottajoules by 1.000000000e+31 to get ergs. To reverse the conversion, multiply a erg value by 1.000000000e-31 to get back to yottajoules.
Frequently asked questions
What is Yottajoule (YJ)?
A yottajoule (YJ) is a metric-prefixed unit of energy equal to 1024 joules, using the SI yotta 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 yottajoules to ergs?
Multiply the yottajoule value by 1.000000000e+31 to get the equivalent in ergs. For example, 5 YJ × 1.000000000e+31 = 5.000000e+31 erg.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+31 is an exact, non-rounded value.
Can I convert ergs back to yottajoules?
Yes. Divide the erg value by 1.000000000e+31, or multiply it by 1.000000000e-31, to get yottajoules.
