This page converts nanofarads into farads using the factor 1e-09, 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.
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. 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. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into farads, which is usually more useful than the bare number.
The formula
nanofarads- The amount you are converting, in nanofarads
1e-09- The exact number of farads in one nanofarad
farads- The converted result
How it works, step by step
- Enter the value in nanofarads.
- It is multiplied by 1e-09, 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
Crystal load capacitor: 0.022 nF in farads
At 0.022 nF (crystal load capacitor), the same quantity in farads is 0.022 × 1e-09 = 2.20000e-11 F. One nanofarad is 1e-09 farads, so the numbers shrink as expected.
Audio coupling capacitor: 1000 nF in farads
At 1000 nF (audio coupling capacitor), the same quantity in farads is 1000 × 1e-09 = 1e-06 F. One nanofarad is 1e-09 farads, so the numbers shrink as expected.
How to read your score
Frequently asked questions
How many farads are in one nanofarad?
Exactly 1e-09. 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 nanofarads to farads?
farads = nanofarads × 1e-09. Reversed, nanofarads = farads ÷ 1e-09, which is the same as multiplying by 1,000,000,000.
Which is the bigger unit, the nanofarad or the farad?
The farad. One nanofarad is only 1e-09 of a farad, so it takes 1e+09 nanofarads 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 nanofarad?
Nanofarads sit in the awkward middle of capacitor labelling: the same part may be printed 100 nF, 0.1 µF or 104.
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.
