About Coulombs per metre
The coulomb per metre (C/m) is the SI coherent unit of linear charge density, equal to 1 A·s·m⁻¹. A typical lightning return stroke carries about 2-5 C/m along the channel; heavily charged surfaces like Van de Graaff sphere surfaces are described in C/m² (surface), but a thin wire coated with 1 C of charge per metre has a C/m linear density. Textbook Gauss's law problems routinely use C/m for infinite line-charge problems. 1 C/m = 10³ mC/m.
About Attocoulombs per metre
The attocoulomb per metre (aC/m) equals 10⁻¹⁸ C/m, the scale for linear charge density in quantum-confined nanostructures. Induced charge along a quantum dot nanowire segment under a modest gate voltage is in the aC/m to fC/m range; charge delocalised along conjugated organic molecules is estimated in aC/m; electron-beam lithography exposure doses on sub-10 nm features translate to aC/m line dosages. 1 aC/m = 10⁻¹⁸ C/m = 10⁻³ fC/m.
