Small ceramic capacitors are marked with a three digit code rather than a printed value, and this calculator decodes it for you. The first two digits are the significant figures and the third is the number of zeros to append, giving a value in picofarads, so a code of 104 means 10 followed by four zeros, which is 100000 picofarads or 0.1 microfarads. This tool reads the code, works out the capacitance, and shows it converted to picofarads, nanofarads and microfarads so you can match it to a schematic or a parts bin. It also accepts an optional tolerance letter. Decoding these by hand is fiddly and easy to slip on, so an instant lookup keeps your builds accurate. Everything is computed locally in your browser as you type.
