Capacitor uF - nF - pF Conversion Chart

 When reading schematics, repairing radios and buying capacitors, you often must convert between uF, nF and pF.
Paper and electrolytic capacitors are usually expressed in terms of uF (microfarads). Short forms for micro farad include
uF, mfd, MFD, MF and uF. Mica capacitors are usually expressed in terms of pF (micromicrofarads) (picofarads).
Short forms for micromicrofarads include pF, mmfd, MMFD, MMF, u uF and pF. A pF is one-millionth of a uF. In
between a pF and a uF is a nF which is one-one thousands of a uF. Converting back and forth between uF, nF
and pF can be co nFusing with all those darn decimal points to worry about. Below is a uF - nF- pF conversion chart.
Just print a copy and tape it to your workbench....it will come in handy. Have fun with your radio restorations.
