One mil equals one thousandth of an inch. (1 mil = .001 ")

So to get an idea if your spark plug gap is set at .032, a 1/4 of that gap equals 8 mils.

This may be a bad example as a of you may not be old enough to remember
when standard plug gap was .032-.035.

A brand new car paint job from factory counting all layers of paint for 2005
are ranging from 3.3-4.8 mils. on average.
