About Coulombs per inch
The coulomb per inch (C/in) equals exactly 1/0.0254 C/m ≈ 39.370 C/m, used in insulation specifications and dielectric withstand testing at the component level. Dielectric tape and insulating sleeve charge retention is sometimes expressed in C/in in US industry datasheets; PCB creepage and clearance charge density specifications for high-voltage designs appear in C/in. 1 C/in = 1/0.0254 C/m ≈ 39.370 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.
