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