How to use Capacitance Converter
- Choose the input and output capacitance units.
- Enter a capacitance, or fill the optional three-digit code to use that marking instead.
- Calculate and review the equivalent values and how the input was interpreted.
Example: Capacitance Converter
Decode a common numeric capacitor marking.
Options
- Capacitor code
- An entered three-digit code replaces the numeric value and source unit. The first two digits form a coefficient in pF and the third is a decimal exponent.
- Decimal places
- Small capacitances expressed in farads may disappear with coarse rounding. Choose 0, 2, 4, 6 or 8 decimal places and check the farad prefix when reviewing a rounded value.

Confirm the marking convention first
Code 104 means 10 × 10⁴ pF, which is 100000 pF or 0.1 µF. This supported convention does not identify tolerance, voltage rating or every manufacturer marking scheme. Leave Code empty to convert the numeric value.
Questions about Capacitance Converter
Why does 104 mean one hundred nanofarads?
The first two digits give 10 and the last gives a factor of 10⁴. That is 100000 pF, equivalent to 100 nF.
Can I read a voltage rating from the code?
No. The supported code describes nominal capacitance only. Check the component’s separate marking or datasheet.
Does a nominal conversion tell me the measured value?
No. Actual capacitance can vary with tolerance and operating conditions. The page converts the entered nominal value.
