Common Use Cases
-
Specifying PCB clearance or dielectric strength in printed circuit boards
-
Describing electric field intensity for wire insulation and connectors
-
Determining test conditions for dielectric breakdown in electronic components
-
Evaluating ambient electric fields for safety and regulatory compliance
-
Characterizing breakdown thresholds in insulating gaps or materials
-
Assessing near-field electric strengths around high-voltage equipment
Tips & Best Practices
-
Confirm units before conversion to ensure accurate interpretation
-
Understand that volt/mil uses a non-SI length unit which may cause slight approximations
-
Use converted SI values for regulatory, safety, and engineering standard comparisons
-
Maintain significant figures especially in high precision applications
Limitations
-
Volt/mil relies on the mil unit (0.001 inch), so exact conversions depend on this definition
-
Large converted values in volt/meter can be less intuitive in everyday use
-
Care is required in precision applications to keep conversion accuracy
Frequently Asked Questions
-
What is the conversion rate from volt/mil to volt/meter?

Key Terminology
-
Volt/mil (V/mil)
-
A unit of electric field strength representing one volt of potential difference across a distance of one mil (0.001 inch), commonly used in electronics.
-
Volt/meter (V/m)
-
The SI unit of electric field strength, reflecting one volt of potential difference across one meter distance.
-
Mil
-
A unit of length equal to one thousandth of an inch (0.001 inch), used especially in electronics for small distance measurements.
