How the formula works
Both yottajoule and yoctojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in yottajoules by 1.000000000e+48 to get yoctojoules. To reverse the conversion, multiply a yoctojoule value by 1.000000000e-48 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 Yoctojoule (yJ)?
A yoctojoule (yJ) is a metric-prefixed unit of energy equal to 10-24 joules, a fraction of a single joule, using the SI yocto prefix.
How do I convert yottajoules to yoctojoules?
Multiply the yottajoule value by 1.000000000e+48 to get the equivalent in yoctojoules. For example, 5 YJ × 1.000000000e+48 = 5.000000e+48 yJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+48 is an exact, non-rounded value.
Can I convert yoctojoules back to yottajoules?
Yes. Divide the yoctojoule value by 1.000000000e+48, or multiply it by 1.000000000e-48, to get yottajoules.
