Capacitance Calculator

Capacitive reactance is an opposition to the change of voltage across an
element. Capacitive reactance
XC is inversely proportional to the signal
frequency
f (or angular frequency ω) and the capacitance C.
1,000,000 pF = 1000 nF = 1 µF = 1 × 10−6 F
  100,000 pF = 100 nF = 0.1 µF = 1 × 10−7 F
    10,000 pF = 10 nF = 0.01 µF = 1 × 10−8 F
      1,000 pF = 1 nF = 0.001 µF = 1 × 10−9 F
        100 pF = 0.1 nF = 0.0001 µF = 1 × 10−10 F
          10 pF = 0.01 nF = 0.00001 µF = 1 × 10−11 F
            1 pF = 0.001 nF = 0.000001 µF = 1 × 10−12 F
