How the formula works
Both decajoule and femtojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decajoules by 1.000000000e+16 to get femtojoules. To reverse the conversion, multiply a femtojoule value by 1.000000000e-16 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 Femtojoule (fJ)?
A femtojoule (fJ) is a metric-prefixed unit of energy equal to 10-15 joules, a fraction of a single joule, using the SI femto prefix.
How do I convert decajoules to femtojoules?
Multiply the decajoule value by 1.000000000e+16 to get the equivalent in femtojoules. For example, 5 daJ × 1.000000000e+16 = 5.000000e+16 fJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+16 is an exact, non-rounded value.
Can I convert femtojoules back to decajoules?
Yes. Divide the femtojoule value by 1.000000000e+16, or multiply it by 1.000000000e-16, to get decajoules.
