What Is This Tool?
This tool converts values between volt per mil (V/mil) and kilovolt per meter (kV/m), both units of electric field strength used in electronics and electrical engineering. It helps translate measurements from an imperial-based unit into an SI standard unit, enabling better communication and compliance with international standards.
How to Use This Tool?
-
Enter the electric field strength value in volt per mil (V/mil).
-
Select the output unit as kilovolt per meter (kV/m).
-
Click the convert button to see the equivalent value in kV/m.
Key Features
-
Converts electric field strength from volt/mil to kilovolt/meter with a precise conversion factor.
-
Browser-based and easy to operate without the need for specialized software.
-
Supports applications in PCB design, insulation testing, and high-voltage engineering.
Examples
-
2 V/mil converts to approximately 78.74 kV/m.
-
0.5 V/mil converts to approximately 19.69 kV/m.
Common Use Cases
-
Specifying dielectric strength and clearance requirements on printed circuit boards.
-
Describing electric field intensities in wire insulation and high-voltage components.
-
Assessing insulation and safety near high-voltage transmission equipment.
-
Defining test levels for dielectric breakdown and EMC testing.
Tips & Best Practices
-
Ensure units correspond to the measured spacing or distance to avoid inaccuracies.
-
Use this tool for unit translation to comply with international engineering and physics standards.
-
Consider calibration and measurement context for precise field strength evaluations.
Limitations
-
Volt/mil is based on the imperial unit of 0.001 inch, which can cause rounding approximations.
-
Environmental factors like humidity and temperature are not accounted for in the conversion.
-
Conversion assumes ideal conditions and uniform field distribution which may differ in practice.
Frequently Asked Questions
-
What does volt per mil measure?
-
Volt per mil measures electric field strength as the potential difference across a distance of one mil (0.001 inch).
-
Why convert volt/mil to kilovolt/meter?
-
Converting to kilovolt/meter translates imperial-based measurements into SI units used widely in engineering and physics.
-
Can environmental conditions affect the conversion accuracy?
-
Yes, factors like humidity and temperature can influence insulation performance and are not considered in the unit conversion.
Key Terminology
-
Volt per mil (V/mil)

A unit of electric field strength representing one volt potential difference over a distance of one mil (0.001 inch).
-
Kilovolt per meter (kV/m)
-
A unit of electric field strength equal to 1,000 volts per meter used to express electric potential gradient in SI units.
-
Electric field strength
-
A measure of the force exerted per unit charge at a point in space, expressed in units like V/mil or kV/m.
