How the formula works
Both microjoule and hectojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microjoules by 1.000000000e-08 to get hectojoules. To reverse the conversion, multiply a hectojoule value by 100000000 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 Hectojoule (hJ)?
A hectojoule (hJ) is a metric-prefixed unit of energy equal to 102 joules, using the SI hecto prefix.
How do I convert microjoules to hectojoules?
Multiply the microjoule value by 1.000000000e-08 to get the equivalent in hectojoules. For example, 5 uJ × 1.000000000e-08 = 5.000000e-08 hJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-08 is an exact, non-rounded value.
Can I convert hectojoules back to microjoules?
Yes. Divide the hectojoule value by 1.000000000e-08, or multiply it by 100000000, to get microjoules.
