Convert Coulombs per foot to Coulombs per centimetre
Convert Coulombs per foot (C/ft) to Coulombs per centimetre (C/cm) instantly and accurately.
Conversion Formula
C/cm = C/ft × 0.03280839895
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.
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.
