How the formula works
Both kilojoule and picojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in kilojoules by 1.000000000e+15 to get picojoules. To reverse the conversion, multiply a picojoule value by 1.000000000e-15 to get back to kilojoules.
Frequently asked questions
What is Kilojoule (kJ)?
A kilojoule (kJ) equals 1,000 joules and is commonly used on nutrition labels outside the United States.
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.
How do I convert kilojoules to picojoules?
Multiply the kilojoule value by 1.000000000e+15 to get the equivalent in picojoules. For example, 5 kJ × 1.000000000e+15 = 5.000000e+15 pJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+15 is an exact, non-rounded value.
Can I convert picojoules back to kilojoules?
Yes. Divide the picojoule value by 1.000000000e+15, or multiply it by 1.000000000e-15, to get kilojoules.
