This page converts nanofarads into millifarads using the factor 1e-06, and shows the reverse figure alongside it. Both units measure how much charge a component stores per volt, which is why one number does the whole job.
One milli farad is one thousandth of a farad (1e-3 farads). Nanofarads sit in the awkward middle of capacitor labelling: the same part may be printed 100 nF, 0.1 µF or 104.
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 millifarads, which is usually more useful than the bare number.
The formula
nanofarads- The amount you are converting, in nanofarads
1e-06- The exact number of millifarads in one nanofarad
millifarads- The converted result
How it works, step by step
- Enter the value in nanofarads.
- It is multiplied by 1e-06, the exact factor between the two units.
- The answer is shown in millifarads, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
Power supply smoothing capacitor: 4.7e+06 nF in millifarads
Power supply smoothing capacitor comes to about 4.7e+06 nF. Multiplying by the factor: 4.7e+06 × 1e-06 = 4.7 mF. Dividing the answer back by 1e-06 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
Motor-run capacitor: 2.5e+04 nF in millifarads
Take motor-run capacitor, roughly 2.5e+04 nF. The conversion is a single multiplication — 2.5e+04 × 1e-06 — giving 0.025 mF. Because the relationship is proportional, doubling the input doubles the answer to 0.05 mF.

Frequently asked questions
How many millifarads are in one nanofarad?
Exactly 1e-06. 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 nanofarads to millifarads?
millifarads = nanofarads × 1e-06. Reversed, nanofarads = millifarads ÷ 1e-06, which is the same as multiplying by 1,000,000.
Which is the bigger unit, the nanofarad or the millifarad?
The millifarad. One nanofarad is only 1e-06 of a millifarad, so it takes 1e+06 nanofarads to make one millifarad.
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 nanofarad?
Nanofarads sit in the awkward middle of capacitor labelling: the same part may be printed 100 nF, 0.1 µF or 104.
What is a millifarad?
One milli farad is one thousandth of a farad (1e-3 farads).
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.
