What Is a Volt per Inch?
A volt per inch is a unit of electric field strength equal to 39.3700787 volts per meter (V/m), the base unit for electric field strength. Equal to 39.3701 V/m. [1]
The volt per inch is classified as a US customary unit of electric field strength. Volts per Inch can be abbreviated as V/in; for example, 1 volt per inch can be written as 1 V/in.
When working with volts per inch (V/in) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, volts per inch (V/in) are widely used across standard electric field strength applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Volt per Millimeter?
A volt per millimeter is a unit of electric field strength equal to 1,000 volts per meter (V/m), the base unit for electric field strength. Insulation dielectric strength unit (1,000 V/m). [2]
The volt per millimeter is classified as a metric and SI-compatible unit of electric field strength. Volts per Millimeter can be abbreviated as V/mm; for example, 1 volt per millimeter can be written as 1 V/mm.
When working with volts per millimeter (V/mm) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, volts per millimeter (V/mm) are widely used across large-scale industrial, bulk, and macro-level electric field strength specifications within SI metric workflows, engineering documentation, and technical data sheets.
When converting electric field strength between volts per inch (V/in) and volts per millimeter (V/mm), keep full floating-point precision (1 V/in = 0.0393701 V/mm; 1 V/mm = 25.4 V/in) during intermediate calculations and round only the final volt per millimeter figure to match your instrument tolerance.
