How the formula works
Both picojoule and zettajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picojoules by 1.000000000e-33 to get zettajoules. To reverse the conversion, multiply a zettajoule value by 1.000000000e+33 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 Zettajoule (ZJ)?
A zettajoule (ZJ) is a metric-prefixed unit of energy equal to 1021 joules, using the SI zetta prefix.
How do I convert picojoules to zettajoules?
Multiply the picojoule value by 1.000000000e-33 to get the equivalent in zettajoules. For example, 5 pJ × 1.000000000e-33 = 5.000000e-33 ZJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-33 is an exact, non-rounded value.
Can I convert zettajoules back to picojoules?
Yes. Divide the zettajoule value by 1.000000000e-33, or multiply it by 1.000000000e+33, to get picojoules.
