Nanofarad (nF) ↔ Microfarad (µF) Calculator
Convert capacitor values instantly between nF and µF (and other common capacitance units).
Tip: For nF to µF, divide by 1000. For µF to nF, multiply by 1000.
What is an nF to µF conversion?
In electronics, capacitor values are often printed in nanofarads (nF) or microfarads (µF). Since these are both metric units of capacitance, converting between them is straightforward. The only trick is remembering the scale: microfarads are 1,000 times larger than nanofarads.
This calculator helps you convert quickly when reading capacitor labels, checking circuit designs, selecting replacement components, or matching values in RC filters, timing circuits, and power decoupling applications.
nF and µF relationship
Core formulas
- 1 µF = 1000 nF
- 1 nF = 0.001 µF
So if you're converting nF to µF, divide by 1000. If you're converting µF to nF, multiply by 1000.
Quick reference table
| nF | µF |
|---|---|
| 1 nF | 0.001 µF |
| 10 nF | 0.01 µF |
| 47 nF | 0.047 µF |
| 100 nF | 0.1 µF |
| 220 nF | 0.22 µF |
| 470 nF | 0.47 µF |
| 1000 nF | 1 µF |
Where this matters in real circuits
1) Decoupling and bypass capacitors
Many digital circuits use 100 nF capacitors near IC power pins. Datasheets sometimes write this as 0.1 µF. Both values are identical.
2) Filter networks
In analog and audio circuits, filter corner frequencies depend on capacitor values. Mixing up nF and µF can shift your cutoff frequency by a factor of 1000, which can break expected behavior.
3) Component replacement
If an old part is marked in nF but your supplier lists µF, this conversion ensures you pick the correct equivalent. You should also match voltage rating, tolerance, and dielectric type when possible.
Common mistakes to avoid
- Confusing mF (millifarad) with µF (microfarad). 1 mF = 1000 µF.
- Typing decimal commas in systems expecting decimal points (the calculator supports both basic formats).
- Ignoring tolerance; a 10% capacitor may vary from nominal value.
- Selecting the wrong unit in design software or simulation tools.
FAQ
Is 0.1 µF the same as 100 nF?
Yes. They are exactly the same capacitance value.
How do I convert 470 nF to µF?
Divide by 1000: 470 nF = 0.47 µF.
How do I convert 2.2 µF to nF?
Multiply by 1000: 2.2 µF = 2200 nF.
Can this calculator convert units besides nF and µF?
Yes. It also supports pF, mF, and F so you can move across common capacitance scales easily.
Final thoughts
Unit conversion in electronics should be quick and error-free. Use this nf uf calculator any time you need to move between nanofarads and microfarads, and keep your designs accurate from schematic to PCB.
