Formula
Formula
F = fF × 1e-15
Multiply any value in femtofarads by 1e-15 to obtain the value in farads.
Worked example
Convert 1e+15 fF to F.
- 01Start with 1e+15 fF.
- 02Multiply by the conversion factor: 1e+15 × 1e-15 = 1 F.
Result1e+15 fF = 1 F

FAQ
What is the conversion factor from fF to F?
1 fF equals 1e-15 F. To convert, multiply the value in femtofarads by 1e-15.
How do I convert 1 fF to F?
1 fF = 1e-15 F. For any value, multiply by 1e-15.
How do I convert F back to fF?
Divide by the same factor — or equivalently, multiply by 1e+15. So 1 F = 1e+15 fF.
When would I need to convert femtofarad to farad?
Capacitance conversions between fF and F 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).
