Conversion Formula
fC/m = C/cm × 1.000000000e+17
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 Femtocoulombs per metre
The femtocoulomb per metre (fC/m) equals 10⁻¹⁵ C/m, arising in scanning probe measurements of charged surface features and in single-molecule electrostatic force microscopy. A single elementary charge (1.6 × 10⁻¹⁹ C) localised on a 1 µm polymer segment gives about 0.16 fC/m; EFM tip-sample interaction models use fC/m-scale induced charge distributions. 1 fC/m = 10⁻¹⁵ C/m = 10⁻³ pC/m.
