Formula
Formula
mF = fF × 1e-12
Multiply any value in femtofarads by 1e-12 to obtain the value in millifarads.
Worked example
Convert 1e+12 fF to mF.
- 01Start with 1e+12 fF.
- 02Multiply by the conversion factor: 1e+12 × 1e-12 = 1 mF.
Result1e+12 fF = 1 mF

FAQ
What is the conversion factor from fF to mF?
1 fF equals 1e-12 mF. To convert, multiply the value in femtofarads by 1e-12.
How do I convert 1 fF to mF?
1 fF = 1e-12 mF. For any value, multiply by 1e-12.
How do I convert mF back to fF?
Divide by the same factor — or equivalently, multiply by 1e+12. So 1 mF = 1e+12 fF.
When would I need to convert femtofarad to millifarad?
Capacitance conversions between fF and mF are needed in power-factor-correction sizing, filter design, sensor electronics and motor-starter specification. Microfarads dominate power capacitor and motor-run/start applications; nanofarads and picofarads cover decoupling and RF circuit design.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
