Convert Volts per inch to Millivolts per centimetre
Convert Volts per inch (V/in) to Millivolts per centimetre (mV/cm) instantly and accurately.
Conversion Formula
mV/cm = V/in × 393.7007874
About Volts per inch
The volt per inch (V/in) equals exactly 1 / 0.0254 V/m ≈ 39.370 V/m, used in North American high-voltage insulation specifications, PCB design rules, and cable withstand-voltage testing. ANSI/IEEE standards quote insulation withstand voltages per inch of creepage distance; PCB high-voltage layout rules specify minimum clearances rated in V/in; US power-supply withstand tests may state a 1 000 V/in dielectric rating. 1 V/in ≈ 39.370 V/m.
About Millivolts per centimetre
The millivolt per centimetre (mV/cm) equals exactly 0.1 V/m, used in electrophoresis, biosensor calibration, and bioelectric stimulation research. Standard DNA gel electrophoresis runs at 5-15 V/cm = 5 000-15 000 mV/cm; transcranial direct-current stimulation (tDCS) produces cortical fields of 0.1-0.5 mV/cm; field-effect biosensors detect analyte-binding events as mV/cm-scale potential gradients. 1 mV/cm = 0.1 V/m.
