To convert microfarads to farads, multiply by 1e-06. That factor is the whole relationship: both units measure how much charge a component stores per volt, so the conversion is a proportion with no offset and no substance-specific constant.
Microfarads cover electrolytics, motor-run capacitors and audio coupling — the values most repair jobs deal with. The farad is the SI unit of capacitance: one coulomb of charge stored per volt applied. A whole farad is enormous, which is why practical parts are labelled in fractions of one.
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 farads so the number you get has something to be compared against.
The formula
microfarads- The amount you are converting, in microfarads
1e-06- The exact number of farads in one microfarad
farads- The converted result
How it works, step by step
- Enter the value in microfarads.
- It is multiplied by 1e-06, the exact factor between the two units.
- The answer is shown in farads, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
Supercapacitor cell: 1e+06 µF in farads
Supercapacitor cell comes to about 1e+06 µF. Multiplying by the factor: 1e+06 × 1e-06 = 1 F. Dividing the answer back by 1e-06 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
Audio coupling capacitor: 1 µF in farads
At 1 µF (audio coupling capacitor), the same quantity in farads is 1 × 1e-06 = 1e-06 F. One microfarad is 1e-06 farads, so the numbers shrink as expected.
How to read your score
Frequently asked questions
How many farads are in one microfarad?
Exactly 1e-06. 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 farads?
farads = microfarads × 1e-06. Reversed, microfarads = farads ÷ 1e-06, which is the same as multiplying by 1,000,000.
Which is the bigger unit, the microfarad or the farad?
The farad. One microfarad is only 1e-06 of a farad, so it takes 1e+06 microfarads to make one farad.
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 farad?
The farad is the SI unit of capacitance: one coulomb of charge stored per volt applied. A whole farad is enormous, which is why practical parts are labelled in fractions of one.
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.
