How the formula works
Both picojoule and terajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picojoules by 1.000000000e-24 to get terajoules. To reverse the conversion, multiply a terajoule value by 1.000000000e+24 to get back to picojoules.
Frequently asked questions
What is Picojoule (pJ)?
A picojoule (pJ) is a metric-prefixed unit of energy equal to 10-12 joules, a fraction of a single joule, using the SI pico 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 picojoules to terajoules?
Multiply the picojoule value by 1.000000000e-24 to get the equivalent in terajoules. For example, 5 pJ × 1.000000000e-24 = 5.000000e-24 TJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-24 is an exact, non-rounded value.
Can I convert terajoules back to picojoules?
Yes. Divide the terajoule value by 1.000000000e-24, or multiply it by 1.000000000e+24, to get picojoules.
