About Newtons per coulomb
The newton per coulomb (N/C) is dimensionally identical to V/m (1 N/C = 1 V/m = 1 kg·m·A⁻¹·s⁻³) and is preferred in force-based electrostatics, where the field is defined directly as E = F/q. Coulomb's law gives the field near a point charge as E = kq/r² naturally in N/C; the unit is standard in introductory physics alongside field-line diagrams. 1 N/C = 1 V/m.
About Volts per inch
The volt per inch (V/in) equals exactly 1 / 0.0254 V/m ≈ 39.370 V/m, used in North American high-voltage insulation specifications, PCB design rules, and cable withstand-voltage testing. ANSI/IEEE standards quote insulation withstand voltages per inch of creepage distance; PCB high-voltage layout rules specify minimum clearances rated in V/in; US power-supply withstand tests may state a 1 000 V/in dielectric rating. 1 V/in ≈ 39.370 V/m.
