How the formula works
Both yoctojoule and yottajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in yoctojoules by 1.000000000e-48 to get yottajoules. To reverse the conversion, multiply a yottajoule value by 1.000000000e+48 to get back to yoctojoules.
Frequently asked questions
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.
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 yoctojoules to yottajoules?
Multiply the yoctojoule value by 1.000000000e-48 to get the equivalent in yottajoules. 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 yottajoules back to yoctojoules?
Yes. Divide the yottajoule value by 1.000000000e-48, or multiply it by 1.000000000e+48, to get yoctojoules.
