Convert Volts per metre to Volts per inch
Convert Volts per metre (V/m) to Volts per inch (V/in) instantly and accurately.
Conversion Formula
V/in = V/m × 0.0254
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 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.
