Conversion Formula
C/ft = fC/m × 3.048000000e-16
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 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.
