Convert Millivolts per metre to Volts per metre
Convert Millivolts per metre (mV/m) to Volts per metre (V/m) instantly and accurately.
Conversion Formula
V/m = 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 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.
