Frequently asked questions
What is the source unit in this conversion?
The source unit is the Attojoule (aJ). Attojoule is 1e-18 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 Attojoule to Femtojoule?
Multiply the Attojoule value by 0.001. For example, 10 aJ × 0.001 = 0.01 fJ.
Is the Attojoule 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 Attojoule needs to be compared with, or reported in, Femtojoule, such as in engineering, scientific, or industrial calculations.
Can I convert Femtojoule back to Attojoule?
Yes. Multiply the Femtojoule value by 1000 to get Attojoule.

About this conversion
This page converts Attojoule (aJ) to Femtojoule (fJ) within the engineering converter.
Attojoule is 1e-18 joule units. Femtojoule is 1e-15 joule units.
The formula is fJ = aJ × 0.001, 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.
