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 foot
The coulomb per foot (C/ft) equals exactly 1/0.3048 C/m ≈ 3.2808 C/m, used in North American electrical engineering for charge per unit length on power cables and conductor specifications. High-voltage DC cable charge density ratings are sometimes quoted in C/ft in ANSI/NEMA specifications; lightning protection standards may express charge density per foot of conductor. 1 C/ft = 1/0.3048 C/m ≈ 3.2808 C/m.
