FAQ
What is the conversion factor from fF to μF?
1 fF equals 1e-9 μF. To convert, multiply the value in femtofarads by 1e-9.
How do I convert 1 fF to μF?
1 fF = 1e-9 μF. For any value, multiply by 1e-9.
How do I convert μF back to fF?
Divide by the same factor — or equivalently, multiply by 1e+9. So 1 μF = 1e+9 fF.
When would I need to convert femtofarad to microfarad?
Capacitance conversions between fF and μF 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).
