About Volts per metre
The volt per metre (V/m) is the SI coherent unit of electric field strength, equal to 1 N/C = 1 kg·m·A⁻¹·s⁻³. The fair-weather atmospheric surface electric field averages 100-200 V/m; a 1 W isotropic antenna produces about 5.5 V/m at 1 m; thunderstorm clouds build surface fields of 10 000-100 000 V/m before lightning discharge. 1 V/m = 1 N/C.
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.
