How the formula works
Both yoctojoule and quectojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in yoctojoules by 1000000 to get quectojoules. To reverse the conversion, multiply a quectojoule value by 0.000001 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 Quectojoule (qJ)?
A quectojoule (qJ) is a metric-prefixed unit of energy equal to 10-30 joules, a fraction of a single joule, using the SI quecto prefix.
How do I convert yoctojoules to quectojoules?
Multiply the yoctojoule value by 1000000 to get the equivalent in quectojoules. For example, 5 yJ × 1000000 = 5.000000e+06 qJ.
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 quectojoules back to yoctojoules?
Yes. Divide the quectojoule value by 1000000, or multiply it by 0.000001, to get yoctojoules.
