Capacitor Values & Units
Capacitors typically have values in either picofarads (pF) or microfarads (μF).
1 pF = .000001 μF
To convert pF to μF, multiply by .000001
Example: 4700 pF = .0047 μF
To convert μF to pF, multiply by 1,000,000
Example: .0033 μF = 3300 pF
Note: Many pieces of vintage equipment referred to capacitance units in micromicrofarads .
This unit is now referred to as picofarads (pF).
The values of film and ceramic disk capacitors are typically marked in picofarads (pF) using a
3 digit number followed by a letter, for example:
The first 2 digits are the two significant values of the capacitance and the 3rd digit is number of following zeroes.
For the above example, the value is 6800 pF = .0068 μF
The letter following the three digits is typically the value tolerance, where:
J = 5% K = 10% M = 20%
