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 inch
The coulomb per inch (C/in) equals exactly 1/0.0254 C/m ≈ 39.370 C/m, used in insulation specifications and dielectric withstand testing at the component level. Dielectric tape and insulating sleeve charge retention is sometimes expressed in C/in in US industry datasheets; PCB creepage and clearance charge density specifications for high-voltage designs appear in C/in. 1 C/in = 1/0.0254 C/m ≈ 39.370 C/m.
