How the formula works
Both microjoule and terajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microjoules by 1.000000000e-18 to get terajoules. To reverse the conversion, multiply a terajoule value by 1.000000000e+18 to get back to microjoules.
Frequently asked questions
What is Microjoule (uJ)?
A microjoule (uJ) is a metric-prefixed unit of energy equal to 10-6 joules, a fraction of a single joule, using the SI micro prefix.
What is Terajoule (TJ)?
A terajoule (TJ) is a metric-prefixed unit of energy equal to 1012 joules, using the SI tera prefix.
How do I convert microjoules to terajoules?
Multiply the microjoule value by 1.000000000e-18 to get the equivalent in terajoules. For example, 5 uJ × 1.000000000e-18 = 5.000000e-18 TJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-18 is an exact, non-rounded value.
Can I convert terajoules back to microjoules?
Yes. Divide the terajoule value by 1.000000000e-18, or multiply it by 1.000000000e+18, to get microjoules.
