Todays capacitors have values given in Nano-Farads (NF) while the many
circuits you will see on this site use Pico-Farad (pf) or Micro-Farad (mfd) to
indicate the value.
The conversion is straight forward and as an aid the following table supplies
the values for any given capacitor regardless of age including those only
identified by a code number.
The last column for code numbers will also have a letter after the code
indicating the tolerance: F=1%,G=2%,J=5%,K=10%,M=20%.
