Formula
Formula
mF = F × 1000
Multiply any value in farads by 1000 to obtain the value in millifarads.
Worked example
Convert 1 F to mF.
- 01Start with 1 F.
- 02Multiply by the conversion factor: 1 × 1000 = 1000 mF.
Result1 F = 1000 mF

FAQ
What is the conversion factor from F to mF?
1 F equals 1000 mF. To convert, multiply the value in farads by 1000.
How do I convert 1 F to mF?
1 F = 1000 mF. For any value, multiply by 1000.
How do I convert mF back to F?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 mF = 0.001 F.
When would I need to convert farad to millifarad?
Capacitance conversions between F 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?
Yes. Both F and mF are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
