This calculator is used to find the value of a capacitor from the 3 digit code printed on its side. Enter the code in the box below and then hit the button to calculate the value of the capacitor.
<p>
If the rightmost digit is zero, then the code may be a value in pF instead of the 3-digit code... example: 100 should indicate 10pF but it may instead be a marking of the actual value of 100pF. If the rightmost digit is not zero, then the value is probably coded. Example: 101 is not 101pF but more likely 100pF.
<p>
If the capacitor code is only 2 digits, then that is certainly the value in picofarads (pF).
