Conversion Formula
N/C = mV/m × 0.001
About Millivolts per metre
The millivolt per metre (mV/m) equals 10⁻³ V/m, used for medium-wave broadcast field-strength measurements and near-field EMC compliance testing. An AM broadcast tower at 1 km produces a field of roughly 100 mV/m; international AM service-area limits specify minimum field strengths of 3-10 mV/m; power-frequency (50/60 Hz) fields near overhead HV lines are a few mV/m. 1 mV/m = 10⁻³ V/m.
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.
