How the formula works
Both terajoule and decajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in terajoules by 100000000000 to get decajoules. To reverse the conversion, multiply a decajoule value by 1.000000000e-11 to get back to terajoules.
Frequently asked questions
What is Terajoule (TJ)?
A terajoule (TJ) is a metric-prefixed unit of energy equal to 1012 joules, using the SI tera prefix.
What is Decajoule (daJ)?
A decajoule (daJ) is a metric-prefixed unit of energy equal to 101 joules, using the SI deca prefix.
How do I convert terajoules to decajoules?
Multiply the terajoule value by 100000000000 to get the equivalent in decajoules. For example, 5 TJ × 100000000000 = 5.000000e+11 daJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 100000000000 is an exact, non-rounded value.
Can I convert decajoules back to terajoules?
Yes. Divide the decajoule value by 100000000000, or multiply it by 1.000000000e-11, to get terajoules.
