How the formula works
Both hectojoule and terajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in hectojoules by 1.000000000e-10 to get terajoules. To reverse the conversion, multiply a terajoule value by 10000000000 to get back to hectojoules.
Frequently asked questions
What is Hectojoule (hJ)?
A hectojoule (hJ) is a metric-prefixed unit of energy equal to 102 joules, using the SI hecto 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 hectojoules to terajoules?
Multiply the hectojoule value by 1.000000000e-10 to get the equivalent in terajoules. For example, 5 hJ × 1.000000000e-10 = 5.000000e-10 TJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-10 is an exact, non-rounded value.
Can I convert terajoules back to hectojoules?
Yes. Divide the terajoule value by 1.000000000e-10, or multiply it by 10000000000, to get hectojoules.
