How to Convert Electric Field Strength Units
Electric field strength is the force per unit charge at a point, equal to the voltage gradient. The SI unit is volt per metre (V/m); dielectric strength of insulation is often given in kV/mm or V/mil.
Every unit on this page is stored as a fixed factor relative to one reference unit, the volt per metre (V/m). Converting is a two step multiply and divide:
- Multiply your value by the factor of the source unit to get the value in V/m.
- Divide that result by the factor of the target unit.

Frequently Asked Questions
What is the SI unit of electric field strength?
The SI unit of electric field strength is the volt per metre (V/m). Electric field strength is the force per unit charge at a point, equal to the voltage gradient.
How do I convert kV/mm to V/mil?
To convert kilovolt per millimetre (kV/mm) to volt per mil (V/mil), multiply the value in kV/mm by 25.4. For example, 1 kV/mm = 25.4 V/mil.
How do I convert V/mil to kV/mm?
To convert volt per mil (V/mil) to kilovolt per millimetre (kV/mm), multiply the value in V/mil by 0.0393701. For example, 1 V/mil = 0.0393701 kV/mm.
How do I convert kV/cm to V/m?
To convert kilovolt per centimetre (kV/cm) to volt per metre (V/m), multiply the value in kV/cm by 100,000. For example, 1 kV/cm = 100,000 V/m.
Can I see a value in every electric field strength unit at once?
Yes. Enter a value and choose the source unit; the "all units" table below the converter instantly lists the equivalent in all 10 supported units. Click any row to make it the target unit.
