volt per mil
Electric field strengthexact by definition
One volt per mil, where a mil is one thousandth of an inch. Since a mil is 2.54×10⁻⁵ m exactly, one V/mil is 39,370.0787… V/m — an exact conversion despite the untidy decimal.
Why it is written : A mil is a thousandth of an inch, not a millimetre and not a milliradian. The collision is real and expensive: reading V/mil as V/mm understates the field by a factor of 39.37.

Where the unit came from
North American wire and film manufacturers specify insulation thickness in mils, so the dielectric strength that goes with it is quoted per mil. The unit survives entirely because the thickness it divides is quoted the same way.
