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 Statcoulombs
The statcoulomb (statC), also called the franklin (Fr) or ESU of charge, is the charge unit in the CGS-Gaussian system. Two point charges of 1 statC separated by 1 cm exert a force of exactly 1 dyne; 1 statC = 1 / (2.99 792 458 × 10⁹) C ≈ 3.336 × 10⁻¹⁰ C (exact, since c is a defined constant). It remains in use in electrostatics textbooks and atomic physics where working without the ε₀ factor simplifies Coulomb-law expressions.
