How the formula works
Both yoctojoule and decajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in yoctojoules by 1.000000000e-25 to get decajoules. To reverse the conversion, multiply a decajoule value by 1.000000000e+25 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 Decajoule (daJ)?
A decajoule (daJ) is a metric-prefixed unit of energy equal to 101 joules, using the SI deca prefix.
How do I convert yoctojoules to decajoules?
Multiply the yoctojoule value by 1.000000000e-25 to get the equivalent in decajoules. For example, 5 yJ × 1.000000000e-25 = 5.000000e-25 daJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-25 is an exact, non-rounded value.
Can I convert decajoules back to yoctojoules?
Yes. Divide the decajoule value by 1.000000000e-25, or multiply it by 1.000000000e+25, to get yoctojoules.
