How the formula works
Both nanojoule and megajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanojoules by 1.000000000e-15 to get megajoules. To reverse the conversion, multiply a megajoule value by 1.000000000e+15 to get back to nanojoules.
Frequently asked questions
What is Nanojoule (nJ)?
A nanojoule (nJ) is a metric-prefixed unit of energy equal to 10-9 joules, a fraction of a single joule, using the SI nano prefix.
What is Megajoule (MJ)?
A megajoule (MJ) is a metric-prefixed unit of energy equal to 106 joules, using the SI mega prefix.
How do I convert nanojoules to megajoules?
Multiply the nanojoule value by 1.000000000e-15 to get the equivalent in megajoules. For example, 5 nJ × 1.000000000e-15 = 5.000000e-15 MJ.
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 megajoules back to nanojoules?
Yes. Divide the megajoule value by 1.000000000e-15, or multiply it by 1.000000000e+15, to get nanojoules.
