How to use the Capacitance Calculator
- Fill in the values you know. Fields already contain typical example values that you can overwrite.
- Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
- Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
- A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.
If a value is missing or does not make sense, the field shows a short message explaining what to fix.
Formulas used
This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

Interpreting your results
After pressing the calculate button, the Capacitance Calculator will display an output that includes the total capacitance and any additional relevant information.
- Total Capacitance: This is the equivalent capacitance of the configuration you selected. For capacitors in parallel, the total capacitance adds up (C_total = C1 + C2 + C3…). For series, it is calculated differently (1/C_total = 1/C1 + 1/C2 + 1/C3…).
- Surge Voltage: Indicates the maximum voltage the capacitor can handle safely, which is crucial to prevent damage.
- Inputting incorrect units. Always verify you are using the same unit for each capacitor (e.g., Farads, microfarads).
- Forgetting to consider the configuration type (parallel vs. series). This drastically changes the output results.
- Neglecting to check the voltage rating against the operational voltage to avoid capacitor failure.
