How the formula works
Both decajoule and exajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decajoules by 1.000000000e-17 to get exajoules. To reverse the conversion, multiply a exajoule value by 1.000000000e+17 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 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 decajoules to exajoules?
Multiply the decajoule value by 1.000000000e-17 to get the equivalent in exajoules. For example, 5 daJ × 1.000000000e-17 = 5.000000e-17 EJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-17 is an exact, non-rounded value.
Can I convert exajoules back to decajoules?
Yes. Divide the exajoule value by 1.000000000e-17, or multiply it by 1.000000000e+17, to get decajoules.
