Capacitance Calculator
⚡ Electricity & magnetism. Use the Capacitance formula to find capacitance, charge, voltage: pick the value you want, type the others, and the answer updates as you go.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Capacitance | F |
| Charge | C |
| Voltage | V |
Worked example
Find the capacitance when Charge = 0.012 C, Voltage = 12 V.
Using C = Q/V: Capacitance = 0.001 F.
Frequently asked questions
What is the formula for Capacitance?
C = Q/V.
What do the letters stand for, and what units are used?
Capacitance in F, Charge in C, Voltage in V.
How do you calculate capacitance?
Put the values into C = Q/V. For example, with Charge = 0.012 C, Voltage = 12 V, capacitance = 0.001 F.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (capacitance, charge, voltage) and fill in the others: it rearranges the formula for you.
