Conversion Formula

C = pC × 1.000000000e-12

About Picocoulombs

The picocoulomb (pC) equals 10⁻¹² C, the standard charge unit for radiation detector pulse heights and precision electrometers. Charge signals from Geiger-Muller tubes, scintillator detectors, and proportional counters are routinely expressed in picocoulombs; a 1 pF capacitor at 1 V holds exactly 1 pC. 1 pC = 10⁻³ nC = 10³ fC.

About Coulombs

The coulomb (C) is the SI derived unit of electric charge, equal to the charge transported by a current of 1 A in 1 s. In the 2019 SI revision it is fixed exactly via the elementary charge: 1 C = 1 / (1.602 176 634 × 10⁻¹⁹) e ≈ 6.241 × 10¹⁸ e. Practical benchmarks: a 1 Ah battery stores 3 600 C; a lightning bolt transfers 1-20 C.
