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 Kilovolts per metre
The kilovolt per metre (kV/m) equals 10³ V/m, the standard unit for power-frequency electric field safety limits and environmental surveys near high-voltage infrastructure. ICNIRP occupational exposure limit for 50 Hz electric fields is 10 kV/m; directly under a 400 kV transmission line the surface field reaches 10-15 kV/m; the Earth's fair-weather atmospheric field averages 0.1-0.2 kV/m. 1 kV/m = 10³ V/m.
