What does volt per mil (V/mil) measure?

Volt per mil measures electric field strength as one volt of potential difference across one mil, commonly used for specifying electronic clearance and insulation.

When should I use microvolt per meter (µ/m)?

Use microvolt per meter to describe very low-level electric fields such as in electromagnetic interference measurements and sensitive receiver monitoring.

Why is the conversion factor between V/mil and µ/m so large?

Because a mil is a very small distance (0.001 inch) compared to one meter, the electric field strength measured per mil converts to a much higher numeric value per meter.

Tips & Best Practices

Ensure the units match your measurement context before converting.
Use this conversion when translating high-intensity fields to very low-level measurements.
Consider the differing distances each unit represents: mils vs. meters.
Be aware of precision limitations due to the large conversion factor.
Apply results appropriately according to the electronic or electromagnetic application.

Limitations

Large differences in unit magnitudes may cause floating-point precision issues.
Volt/mil is suited for high-field, short distance measurements; microvolt/meter for low-level, long distance fields.
Direct comparisons require understanding of measurement context and conditions.
