How the formula works
Both femtojoule and decijoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtojoules by 1.000000000e-14 to get decijoules. To reverse the conversion, multiply a decijoule value by 100000000000000 to get back to femtojoules.
Frequently asked questions
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.
What is Decijoule (dJ)?
A decijoule (dJ) is a metric-prefixed unit of energy equal to 10-1 joules, a fraction of a single joule, using the SI deci prefix.
How do I convert femtojoules to decijoules?
Multiply the femtojoule value by 1.000000000e-14 to get the equivalent in decijoules. For example, 5 fJ × 1.000000000e-14 = 5.000000e-14 dJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-14 is an exact, non-rounded value.
Can I convert decijoules back to femtojoules?
Yes. Divide the decijoule value by 1.000000000e-14, or multiply it by 100000000000000, to get femtojoules.
