What Is This Tool?

This converter helps transform electric field strength values measured in volt per inch (V/in), an imperial unit, into volt per mil (V/mil), a finer unit mainly used in electronics and electrical engineering. It enables precise adjustments necessary for defining insulation and clearance standards.

How to Use This Tool?

  • Enter the electric field strength value in volt per inch (V/in).
  • Select volt per mil (V/mil) as the target unit for conversion.
  • Apply the conversion formula, multiplying the V/in value by 0.001.
  • Review the converted output in volt per mil to use in your electronics or high-voltage projects.

Key Features

  • Simple conversion from V/in to V/mil using a direct multiplication formula.
  • Covers electric field strength measurements relevant to industrial and electronic applications.
  • Browser-based and easy to use without needing complex calculations.
  • Supports proper unit transitions for accurate electric field and insulation specifications.

Examples

  • Convert 5 V/in: 5 × 0.001 = 0.005 V/mil.
  • Convert 100 V/in: 100 × 0.001 = 0.1 V/mil.

Common Use Cases

  • Defining dielectric strength or breakdown ratings of insulating materials in imperial units.
  • Setting proper clearance and spacing in high-voltage equipment and power distribution hardware.
  • Designing electrode gaps, spark gaps, and gas-discharge devices in labs or industrial environments.
  • Specifying required insulation clearance on printed circuit boards and electronic assemblies.
  • Describing electric field intensity for wire insulation, connectors, and components.
  • Testing conditions for dielectric breakdown or flashover in component qualification and PCB testing.

Tips & Best Practices

  • Confirm units before converting to avoid misinterpretation of electric field measurements.
  • Use the precise formula: multiply V/in values by 0.001 to get V/mil values accurately.
  • Consider the smaller scale of volt per mil for fine detailing in PCB design and insulation requirements.
  • Be cautious that large values in V/in become smaller when converted to V/mil due to unit size differences.
  • Verify measurement accuracy of voltage and distances to prevent design or safety issues.

Limitations

  • Volt/mil is a smaller unit than volt/inch, so converted values become much smaller numerically.
  • Precision depends on accurate measurement of voltage and distance parameters.
  • Incorrect conversions may lead to errors in design or safety hazards in electrical and electronic systems.

Frequently Asked Questions

What does volt per inch (V/in) measure?
Volt per inch measures electric field strength as one volt of potential difference across one inch of distance.

How is volt per mil (V/mil) different from volt per inch (V/in)?
Volt per mil measures electric field strength over a smaller distance unit, one mil, where 1 mil is 0.001 inch, making it finer for precision electronics and insulation measurements.

What is the formula to convert from V/in to V/mil?
The conversion formula is 1 Volt/inch equals 0.001 Volt/mil, so multiply the V/in value by 0.001 to get the result in V/mil.

Key Terminology

Volt per inch (V/in)
A unit of electric field strength indicating one volt of potential difference across one inch.
Volt per mil (V/mil)
A unit of electric field strength representing one volt of potential difference over one mil (0.001 inch).
Electric Field Strength
A measure of the electric potential gradient per unit distance indicating the force exerted per unit charge.
