This Series Capacitor Calculator determines a circuit's total series capacitance. Up to ten different capacitor values can be entered into this calculator. Simply enter the values of the capacitors you have and leave the rest of the fields blank to calculate the total capacitance of less than 10 capacitors. If you want to calculate the series capacitance of three capacitors, for example, fill in the first three boxes and leave the rest blank.

For those three capacitors, the calculator can calculate the total series capacitance. If you need to measure the series capacitance of more than ten capacitors, begin with the first ten and calculate the equivalent series capacitance. Place this result in one of the boxes, and the remaining capacitors in series should be placed in the other boxes. The effect would be the same as if all of the capacitors were measured at the same time.

You can specify whether capacitance is measured in farads (F), millifarads (mF), microfarads (μF), nanofarads (nF), or picofarads (pF). 0.001 F (10⁻³) equals 1 mF. 0.000001 F (10⁻⁶) equals 1 μF. 0.000000001 F (10⁻⁹) equals 1 nF. 0.000000000001 F (10⁻¹²) equals 1 pF. You can enter the capacitance of any device.

Based on the formula above, this calculator computes the total capacitance. The result is given in farads (F).

Capacitors in series: (1/CTOTAL) = (1/C1) + (1/C2) + (1/C3) ...
Capacitors in parallel: CTOTAL = C1 + C2 + C3 ...
