Convert Volts per inch to Megavolts per metre
Convert Volts per inch (V/in) to Megavolts per metre (MV/m) instantly and accurately.
Conversion Formula
MV/m = V/in × 3.937007874e-5
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 Megavolts per metre
The megavolt per metre (MV/m) equals 10⁶ V/m, the scale for accelerating gradients in particle accelerators, internal fields in semiconductor devices, and piezoelectric actuator operation. RF linear accelerator cavities achieve 20-100 MV/m; CMOS gate-oxide fields at 1.8 V across 2 nm SiO₂ are about 900 MV/m; piezoelectric stack actuators operate at 1-3 MV/m. 1 MV/m = 10⁶ V/m.
