How the formula works
Both joule and yottajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in joules by 1.000000000e-24 to get yottajoules. To reverse the conversion, multiply a yottajoule value by 1.000000000e+24 to get back to joules.
Frequently asked questions
What is Joule (J)?
The joule (J) is the SI derived unit of energy, equal to the work done when a force of one newton acts over one meter.
What is Yottajoule (YJ)?
A yottajoule (YJ) is a metric-prefixed unit of energy equal to 1024 joules, using the SI yotta prefix.
How do I convert joules to yottajoules?
Multiply the joule value by 1.000000000e-24 to get the equivalent in yottajoules. For example, 5 J × 1.000000000e-24 = 5.000000e-24 YJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-24 is an exact, non-rounded value.
Can I convert yottajoules back to joules?
Yes. Divide the yottajoule value by 1.000000000e-24, or multiply it by 1.000000000e+24, to get joules.
