How the formula works
Both hectojoule and quectojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in hectojoules by 1.000000000e+32 to get quectojoules. To reverse the conversion, multiply a quectojoule value by 1.000000000e-32 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 Quectojoule (qJ)?
A quectojoule (qJ) is a metric-prefixed unit of energy equal to 10-30 joules, a fraction of a single joule, using the SI quecto prefix.
How do I convert hectojoules to quectojoules?
Multiply the hectojoule value by 1.000000000e+32 to get the equivalent in quectojoules. For example, 5 hJ × 1.000000000e+32 = 5.000000e+32 qJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+32 is an exact, non-rounded value.
Can I convert quectojoules back to hectojoules?
Yes. Divide the quectojoule value by 1.000000000e+32, or multiply it by 1.000000000e-32, to get hectojoules.
