How to use it
- Type the value in the microfarads box.
- Read the result in farads as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
F = µF × 0.000001
Multiply the value in microfarads by 0.000001 to get farads.
Example
To convert 25 µF to farads: 25 × 0.000001 = 0.000025 F.

About the units
- Microfarad
- A microfarad is exactly one millionth of a farad, the usual unit for motor, air conditioner and electrolytic capacitors.
- Farad
- The SI unit of capacitance: a capacitor that stores one coulomb at one volt has one farad, so 1 F = 1 C/V.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many farads are in one microfarad?
1 µF = 0.000001 F exactly.
How do I convert microfarads to farads?
Use F = µF × 0.000001. For example, 25 µF = 0.000025 F.
How many microfarads are in one farad?
1 F = 1,000,000 µF.
How do I read the code 104 on a capacitor?
The first two digits are the value and the third is the number of zeros in picofarads, so 104 means 100000 pF, which is 100 nF or 0.1 µF.
What does MFD mean on AC and motor capacitors?
It is an old abbreviation for microfarad, not megafarad, so a capacitor marked 35 MFD is 35 µF.
