How the formula works
Both decajoule and attojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decajoules by 1.000000000e+19 to get attojoules. To reverse the conversion, multiply a attojoule value by 1.000000000e-19 to get back to decajoules.
Frequently asked questions
What is Decajoule (daJ)?
A decajoule (daJ) is a metric-prefixed unit of energy equal to 101 joules, using the SI deca prefix.
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.
How do I convert decajoules to attojoules?
Multiply the decajoule value by 1.000000000e+19 to get the equivalent in attojoules. For example, 5 daJ × 1.000000000e+19 = 5.000000e+19 aJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+19 is an exact, non-rounded value.
Can I convert attojoules back to decajoules?
Yes. Divide the attojoule value by 1.000000000e+19, or multiply it by 1.000000000e-19, to get decajoules.
