About Microcoulombs per metre
The microcoulomb per metre (µC/m) equals 10⁻⁶ C/m, the practical unit for high-voltage transmission line charge density and surface charge on dielectric films. A 400 kV overhead transmission line has a linear charge density of about 4-8 µC/m; triboelectrically charged polymer films carry surface charge equivalent to 1-100 µC/m along a strip; Van de Graaff belt charge densities are in this range. 1 µC/m = 10⁻⁶ C/m = 10⁻³ mC/m.
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.
