Convert Coulombs per centimetre to Coulombs per inch
Convert Coulombs per centimetre (C/cm) to Coulombs per inch (C/in) instantly and accurately.
Conversion Formula
C/in = C/cm × 2.54
About Coulombs per centimetre
The coulomb per centimetre (C/cm) equals exactly 100 C/m, used in high-energy particle physics and pulsed-power engineering. Particle accelerator beam current densities along the beam axis are quoted in C/cm for high-intensity bunches; pulsed lightning-simulator spark channels carry several C/cm at peak current; field-emission cathode models describe space-charge limited current in C/cm. 1 C/cm = 100 C/m = 10⁻² kC/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.
