Volt per Inch

V/in

Definition

The Volt per Inch (V/in) equals approximately 39.37 volts per meter, providing a convenient imperial unit for measuring electric field strengths. This unit is commonly used in North American electrical engineering and applications using imperial measurements.

History/Origin

The volt per inch unit developed from the practical need to express electric field strengths in imperial units, particularly in North American electrical engineering. It became standard in applications where inch-scale measurements were more convenient than metric units.

Current Use

Volt per inch is commonly used in North American electrical engineering, electrical testing, and applications where imperial units are preferred. It is particularly useful in electrical equipment design and testing in the United States and Canada.

Volt per Mil

V/mil

Definition

The Volt per Mil (V/mil) equals approximately 39,370 volts per meter, where a mil is one thousandth of an inch. This unit is used in electrical insulation testing and applications involving very thin materials with high electric field strengths.

History/Origin

The volt per mil unit became important in electrical insulation testing and the study of electrical breakdown in thin materials. The mil unit (0.001 inch) is commonly used in electrical engineering for measuring very small distances, particularly in insulation specifications.

Current Use

Volt per mil is extensively used in electrical insulation testing, capacitor design, and the study of electrical breakdown in thin materials. It is particularly important in the electrical industry for specifying insulation requirements and testing electrical equipment.
