Capacitor Charge from Capacitance and Voltage Calculator

Q = C · V — definition of capacitance.

Compute the electric charge stored on a parallel-plate (or any) capacitor from its capacitance and the voltage across its plates: Q = C · V. Reports the result in coulombs, micro-coulombs, and the corresponding number of elementary charges (Q / e).
