Convert Millivolts per metre to Kilovolts per centimetre
Convert Millivolts per metre (mV/m) to Kilovolts per centimetre (kV/cm) instantly and accurately.
Conversion Formula
kV/cm = mV/m × 1.000000000e-8
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 Kilovolts per centimetre
The kilovolt per centimetre (kV/cm) equals exactly 10⁵ V/m = 100 kV/m, the practical unit for high-voltage insulation breakdown tests, gas discharge thresholds, and electrostatic process engineering. Air breakdown at standard conditions is about 30 kV/cm; transformer mineral oil withstands 10-20 kV/cm; XLPE power cable insulation is rated 20-40 kV/cm; electrostatic paint spraying operates at 5-15 kV/cm. 1 kV/cm = 10⁵ V/m.
