Capacitors In Parallel Calculator

Summary

Add up to 10 capacitor values to get total parallel capacitance instantly.

How it works

1. Select the number of capacitors in your parallel circuit.
2. Enter each capacitor value and choose its unit (pF, nF, µF, mF, or F).
3. Click Calculate — the tool sums all values: C_total = C1 + C2 + … + Cn.
4. Results are shown in all common units so you can pick the most convenient one.
5. Use Reset to clear all inputs and start a new calculation.

Use cases

• Design filter or bypass capacitor banks in PCB layouts.
• Verify combined capacitance before soldering a parallel cap array.
• Study circuit theory and confirm textbook parallel-cap problems.
• Size decoupling capacitors for power-supply stabilization.
• Check energy storage capacity (E = ½CV²) for a capacitor bank.
• Convert between pF, nF, and µF while summing values.
