Frequently asked questions
What is the source unit in this conversion?
The source unit is the Millijoule (mJ). Millijoule is 0.001 joule units.
What is the destination unit in this conversion?
The destination unit is the Femtojoule (fJ). Femtojoule is 1e-15 joule units.
How do I convert Millijoule to Femtojoule?
Multiply the Millijoule value by 1000000000000. For example, 10 mJ × 1000000000000 = 10000000000000 fJ.
Is the Millijoule to Femtojoule conversion exact?
Yes. Both units belong to the same engineering measurement family (energy), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in Millijoule needs to be compared with, or reported in, Femtojoule, such as in engineering, scientific, or industrial calculations.
Can I convert Femtojoule back to Millijoule?
Yes. Multiply the Femtojoule value by 0 to get Millijoule.

About this conversion
This page converts Millijoule (mJ) to Femtojoule (fJ) within the engineering converter.
Millijoule is 0.001 joule units. Femtojoule is 1e-15 joule units.
The formula is fJ = mJ × 1000000000000, based on each unit's fixed relationship to the energy base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
