About this calculator
Capacitance C measures how much charge a capacitor stores per volt: C = Q/V. For parallel plates: C = ε₀A/d (ε₀ is vacuum permittivity, 8.854 × 10⁻¹² F/m). Real capacitors use dielectric materials between plates which multiply C by a relative permittivity κ.
Frequently asked
1 F is 1 Coulomb per Volt — an enormous amount of charge per volt. Most circuits use µF (10⁻⁶ F), nF (10⁻⁹ F), or pF (10⁻¹² F).
