Convert Coulombs per inch (C/in) to Gigacoulombs per metre (GC/m) instantly and accurately.
Conversion Formula
GC/m = C/in × 3.937007874e-8
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.
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.
