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 Gigacoulombs per metre
The gigacoulomb per metre (GC/m) equals 10⁹ C/m, a value with no engineering realisation but used in astrophysical and cosmological electromagnetic models. Magnetar magnetic fields, pulsar magnetosphere current sheet charge densities, and theoretical cosmic string electromagnetic scenarios are described at GC/m scales in research literature. 1 GC/m = 10⁹ C/m = 10³ MC/m.
