How the formula works
Both decajoule and zettajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decajoules by 1.000000000e-20 to get zettajoules. To reverse the conversion, multiply a zettajoule value by 1.000000000e+20 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 Zettajoule (ZJ)?
A zettajoule (ZJ) is a metric-prefixed unit of energy equal to 1021 joules, using the SI zetta prefix.
How do I convert decajoules to zettajoules?
Multiply the decajoule value by 1.000000000e-20 to get the equivalent in zettajoules. For example, 5 daJ × 1.000000000e-20 = 5.000000e-20 ZJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-20 is an exact, non-rounded value.
Can I convert zettajoules back to decajoules?
Yes. Divide the zettajoule value by 1.000000000e-20, or multiply it by 1.000000000e+20, to get decajoules.
