Convert Volts per inch to Gigavolts per metre
Convert Volts per inch (V/in) to Gigavolts per metre (GV/m) instantly and accurately.
Conversion Formula
GV/m = V/in × 3.937007874e-8
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 Gigavolts per metre
The gigavolt per metre (GV/m) equals 10⁹ V/m, the scale for avalanche breakdown in semiconductor junctions, electron field emission from metal tips, and intense laser-pulse focal fields. Silicon p-n junction avalanche fields are 0.3-0.5 GV/m; electron field emission from tungsten tips begins near 1-5 GV/m; intense femtosecond laser pulses produce peak fields exceeding 1 GV/m in the focal volume. 1 GV/m = 10⁹ V/m.
