Convert Volts per inch to Volts per centimetre
Convert Volts per inch (V/in) to Volts per centimetre (V/cm) instantly and accurately.
Conversion Formula
V/cm = V/in × 0.3937007874
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 Volts per centimetre
The volt per centimetre (V/cm) equals exactly 100 V/m, the practical unit for electrophoresis fields, thin-film electrical measurements, and solid dielectric breakdown specifications. Standard agarose gel electrophoresis runs at 5-15 V/cm; SiO₂ gate-oxide breakdown field is about 10 MV/cm = 10⁹ V/m; electro-osmotic flow in microfluidics is driven at 10-100 V/cm. 1 V/cm = 100 V/m.
