mC/m = fC/m × 1.000000000e-12
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.
About Millicoulombs per metre
The millicoulomb per metre (mC/m) equals 10⁻³ C/m, the scale for charge on highly loaded triboelectric surfaces, electret films, and return-stroke lightning channel segments. Industrial electret microphone films carry surface charge densities of 0.1-10 mC/m², which corresponds to similar values per metre along a thin strip; return-stroke lightning channel charge is 1-10 mC/m distributed along the leader. 1 mC/m = 10⁻³ C/m = 10³ µC/m.
