Capacitance Conversion Chart
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:

1F = 1,000 mF or 10x103mF
1F = 1,000,000 uF or 10x106uF
1F = 1,000,000,000 nF or 10x109nF
1F = 1,000,000,000,000 pF or 10x1012pF
