Conversion Formula
pC = aC × 1.000000000e-6
About Attocoulombs
The attocoulomb (aC) equals 10⁻¹⁸ C, sitting between the elementary charge and the femtocoulomb. It arises in ultra-sensitive charge measurements: single-electron transistors, quantum capacitance probing of graphene and 2D materials, and scanning tunnelling microscopy where tip-sample charge exchange is tracked at this scale. 1 aC = 10⁻³ fC ≈ 6.24 e.
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.
