About Coulombs per inch
The coulomb per inch (C/in) equals exactly 1/0.0254 C/m ≈ 39.370 C/m, used in insulation specifications and dielectric withstand testing at the component level. Dielectric tape and insulating sleeve charge retention is sometimes expressed in C/in in US industry datasheets; PCB creepage and clearance charge density specifications for high-voltage designs appear in C/in. 1 C/in = 1/0.0254 C/m ≈ 39.370 C/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.
