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.
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.
