How to use it
- Type the value in the farads box.
- Read the result in microfarads as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
µF = F × 1,000,000
Multiply the value in farads by 1,000,000 to get microfarads.
Example
To convert 25 F to microfarads: 25 × 1,000,000 = 25,000,000 µF.

About the units
- Farad
- The SI unit of capacitance: a capacitor that stores one coulomb at one volt has one farad, so 1 F = 1 C/V.
- Microfarad
- A microfarad is exactly one millionth of a farad, the usual unit for motor, air conditioner and electrolytic capacitors.
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 microfarads are in one farad?
1 F = 1,000,000 µF exactly.
How do I convert farads to microfarads?
Use µF = F × 1,000,000. For example, 25 F = 25,000,000 µF.
How many farads are in one microfarad?
1 µF = 0.000001 F.
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.
