How to Convert Volts per Millimeter to Volts per Inch
To convert volts per millimeter to volts per inch, multiply the electric field strength by the following conversion ratio: 25.4 volts per inch/volt per millimeter.
Since one volt per millimeter is equal to 25.4 volts per inch, you can use this simple formula to convert:
The electric field strength in volts per inch is equal to the electric field strength in volts per millimeter multiplied by 25.4.
For example, here's how to convert 5 volts per millimeter to volts per inch using the formula above.
How Many Volts per Inch Are in a Volt per Millimeter?
There are 25.4 volts per inch in a volt per millimeter, which is why we use this value in the formula above.
Our volt per millimeter to volt per inch calculator automatically converts your electric field strength measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Volts per Millimeter and volts per inch are both units used to measure electric field strength. Keep reading to learn more about each unit.
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). [1]
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.
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. [2]
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.
When converting electric field strength between volts per millimeter (V/mm) and volts per inch (V/in), keep full floating-point precision (1 V/mm = 25.4 V/in; 1 V/in = 0.0393701 V/mm) during intermediate calculations and round only the final volt per inch figure to match your instrument tolerance.
