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 Nanocoulombs per metre
The nanocoulomb per metre (nC/m) equals 10⁻⁹ C/m, the scale for DNA backbone charge density and strongly gated carbon nanotube charge. B-form DNA carries approximately -2 elementary charges per 0.34 nm base pair spacing, giving an intrinsic linear charge density of about -0.94 nC/m; strongly biased nanotube transistors reach several nC/m. 1 nC/m = 10⁻⁹ C/m = 10⁻³ µC/m.
