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 Picocoulombs per metre
The picocoulomb per metre (pC/m) equals 10⁻¹² C/m, the scale for charge induced on carbon nanotubes by gate electrodes and for lightly charged polymer chains. A metallic single-wall carbon nanotube at a gate bias of a few volts carries about 10-100 pC/m; weakly charged polyelectrolytes in high-salt solution have effective linear charge densities of 1-100 pC/m after ion condensation. 1 pC/m = 10⁻¹² C/m = 10⁻³ nC/m.
