How the formula works
Both terajoule and decijoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in terajoules by 10000000000000 to get decijoules. To reverse the conversion, multiply a decijoule value by 1.000000000e-13 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 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 terajoules to decijoules?
Multiply the terajoule value by 10000000000000 to get the equivalent in decijoules. For example, 5 TJ × 10000000000000 = 5.000000e+13 dJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 10000000000000 is an exact, non-rounded value.
Can I convert decijoules back to terajoules?
Yes. Divide the decijoule value by 10000000000000, or multiply it by 1.000000000e-13, to get terajoules.
