One millifarad is exactly 0.001 farads, so converting millifarads to farads is a single multiplication. Enter any figure and the result appears as you type — the arithmetic runs in your browser, so nothing is sent anywhere.
The farad is the SI unit of capacitance: one coulomb of charge stored per volt applied. A whole farad is enormous, which is why practical parts are labelled in fractions of one. One milli farad is one thousandth of a farad (1e-3 farads).
Capacitor labelling. The same part may be printed 100 nF, 0.1 uF, or the three-digit code 104, and all three mean the same component. Nanofarads are the awkward middle: European schematics favour nF, American ones favour uF. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into farads, which is usually more useful than the bare number.
The formula
millifarads- The amount you are converting, in millifarads
0.001- The exact number of farads in one millifarad
farads- The converted result
How it works, step by step
- Enter the value in millifarads.
- It is multiplied by 0.001, the exact factor between the two units.
- The answer is shown in farads, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
Supercapacitor cell: 1000 mF in farads
Take supercapacitor cell, roughly 1000 mF. The conversion is a single multiplication — 1000 × 0.001 — giving 1 F. Because the relationship is proportional, doubling the input doubles the answer to 2 F.
Audio coupling capacitor: 0.001 mF in farads
Audio coupling capacitor comes to about 0.001 mF. Multiplying by the factor: 0.001 × 0.001 = 1e-06 F. Dividing the answer back by 0.001 returns the figure you started with, which is the quickest way to check you have the factor the right way up.

Frequently asked questions
How many farads are in one millifarad?
Exactly 0.001. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert millifarads to farads?
farads = millifarads × 0.001. Reversed, millifarads = farads ÷ 0.001, which is the same as multiplying by 1000.
Which is the bigger unit, the millifarad or the farad?
The farad. One millifarad is only 0.001 of a farad, so it takes 1000 millifarads to make one farad.
What does this quantity actually measure?
Both units measure how much charge a component stores per volt. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a millifarad?
One milli farad is one thousandth of a farad (1e-3 farads).
What is a farad?
The farad is the SI unit of capacitance: one coulomb of charge stored per volt applied. A whole farad is enormous, which is why practical parts are labelled in fractions of one.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
