Formula
Formula
fF = mF × 1e+12
Multiply any value in millifarads by 1e+12 to obtain the value in femtofarads.
Worked example
Convert 1 mF to fF.
- 01Start with 1 mF.
- 02Multiply by the conversion factor: 1 × 1e+12 = 1e+12 fF.
Result1 mF = 1e+12 fF

FAQ
What is the conversion factor from mF to fF?
1 mF equals 1e+12 fF. To convert, multiply the value in millifarads by 1e+12.
How do I convert 1 mF to fF?
1 mF = 1e+12 fF. For any value, multiply by 1e+12.
How do I convert fF back to mF?
Divide by the same factor — or equivalently, multiply by 1e-12. So 1 fF = 1e-12 mF.
When would I need to convert millifarad to femtofarad?
Capacitance conversions between mF and fF 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).
