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 Millicoulombs per metre
The millicoulomb per metre (mC/m) equals 10⁻³ C/m, the scale for charge on highly loaded triboelectric surfaces, electret films, and return-stroke lightning channel segments. Industrial electret microphone films carry surface charge densities of 0.1-10 mC/m², which corresponds to similar values per metre along a thin strip; return-stroke lightning channel charge is 1-10 mC/m distributed along the leader. 1 mC/m = 10⁻³ C/m = 10³ µC/m.
