How the formula works
Both attojoule and yoctojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attojoules by 1000000 to get yoctojoules. To reverse the conversion, multiply a yoctojoule value by 0.000001 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 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 attojoules to yoctojoules?
Multiply the attojoule value by 1000000 to get the equivalent in yoctojoules. For example, 5 aJ × 1000000 = 5.000000e+06 yJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1000000 is an exact, non-rounded value.
Can I convert yoctojoules back to attojoules?
Yes. Divide the yoctojoule value by 1000000, or multiply it by 0.000001, to get attojoules.
