This page converts millifarads into nanofarads using the factor 1,000,000, 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. Below the calculator there is a step table for the values people look up most, and a second table putting real how much charge a component stores per volt figures into nanofarads so the number you get has something to be compared against.
The formula
millifarads- The amount you are converting, in millifarads
1,000,000- The exact number of nanofarads in one millifarad
nanofarads- The converted result
How it works, step by step
- Enter the value in millifarads.
- It is multiplied by 1,000,000, the exact factor between the two units.
- The answer is shown in nanofarads, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
Power supply smoothing capacitor: 4.7 mF in nanofarads
Take power supply smoothing capacitor, roughly 4.7 mF. The conversion is a single multiplication — 4.7 × 1e+06 — giving 4.7e+06 nF. Because the relationship is proportional, doubling the input doubles the answer to 9.4e+06 nF.
Supercapacitor cell: 1000 mF in nanofarads
Take supercapacitor cell, roughly 1000 mF. The conversion is a single multiplication — 1000 × 1e+06 — giving 1e+09 nF. Because the relationship is proportional, doubling the input doubles the answer to 2e+09 nF.

Frequently asked questions
How many nanofarads are in one millifarad?
Exactly 1,000,000. 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 nanofarads?
nanofarads = millifarads × 1,000,000. Reversed, millifarads = nanofarads ÷ 1,000,000, which is the same as multiplying by 1e-06.
Which is the bigger unit, the millifarad or the nanofarad?
The millifarad. One millifarad equals 1e+06 nanofarads.
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 nanofarad?
Nanofarads sit in the awkward middle of capacitor labelling: the same part may be printed 100 nF, 0.1 µF or 104.
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.
