Convert Femtofarad to Millifarad
Input the number of femtofarads you want to convert to millifarads.
How to Convert Femtofarads to Millifarads
The femtofarad and millifarad are both units of capacitance. By definition, 1 millifarad equals exactly 1e21 femtofarads. This means to convert femtofarads to millifarads, you divide by 1e21.
Formula
Step-by-Step Example
Convert 5 fF to millifarads:
We need to convert femtofarads to millifarads
Since 1 mF = 1e21 fF, divide by 1e21
5 ÷ 1e21 = 5e-21
5 fF = 5e-21 mF

About These Units
Femtofarad (fF)
A femtofarad (fF) equals 10⁻¹⁵ farads or 0.001 picofarads. Used in integrated circuit design, parasitic capacitance calculations, and semiconductor modeling. MOSFET gate capacitance is typically 10-100 fF. Critical for high-speed digital circuit timing.
Millifarad (mF)
A millifarad (mF) equals 0.001 farads or 1,000 microfarads. Found in large electrolytic capacitors for power supplies, audio equipment, and motor start capacitors. Supercapacitors range from 0.1 to 5,000+ mF. Also written as 1000 µF.
