This page converts microfarads into nanofarads using the factor 1000, 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.
Microfarads cover electrolytics, motor-run capacitors and audio coupling — the values most repair jobs deal with. 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. The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in nanofarads, so you can sanity-check whether your answer is a plausible size.
The formula
microfarads- The amount you are converting, in microfarads
1000- The exact number of nanofarads in one microfarad
nanofarads- The converted result
How it works, step by step
- Enter the value in microfarads.
- It is multiplied by 1000, 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: 4700 µF in nanofarads
At 4700 µF (power supply smoothing capacitor), the same quantity in nanofarads is 4700 × 1000 = 4.7e+06 nF. One microfarad is 1000 nanofarads, so the numbers grow as expected.
Audio coupling capacitor: 1 µF in nanofarads
Take audio coupling capacitor, roughly 1 µF. The conversion is a single multiplication — 1 × 1000 — giving 1000 nF. Because the relationship is proportional, doubling the input doubles the answer to 2000 nF.
How to read your score
Frequently asked questions
How many nanofarads are in one microfarad?
Exactly 1000. 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 microfarads to nanofarads?
nanofarads = microfarads × 1000. Reversed, microfarads = nanofarads ÷ 1000, which is the same as multiplying by 0.001.
Which is the bigger unit, the microfarad or the nanofarad?
The microfarad. One microfarad equals 1000 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 microfarad?
Microfarads cover electrolytics, motor-run capacitors and audio coupling — the values most repair jobs deal with.
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.
