How the formula works
Both decijoule and exajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decijoules by 1.000000000e-19 to get exajoules. To reverse the conversion, multiply a exajoule value by 1.000000000e+19 to get back to decijoules.
Frequently asked questions
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.
What is Exajoule (EJ)?
A exajoule (EJ) is a metric-prefixed unit of energy equal to 1018 joules, using the SI exa prefix.
How do I convert decijoules to exajoules?
Multiply the decijoule value by 1.000000000e-19 to get the equivalent in exajoules. For example, 5 dJ × 1.000000000e-19 = 5.000000e-19 EJ.
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 exajoules back to decijoules?
Yes. Divide the exajoule value by 1.000000000e-19, or multiply it by 1.000000000e+19, to get decijoules.
