RE: Shade cloth percentage

From: Ron McHatton rmchatton at photocircuits.com> on 2002.05.22 at 16:07:30(8850) Susan: The measurement of plastic films in mils in the US refers to thousandths of an inch. A 7 mil film is .007 inch thick. The same thing is true in the US with other measurements in mils. The spec on the distributor points in your car (if it has a distributor) or the spark plug gap is measured in thousandths and expressed as mils. Its confusing, since in other parts of the world, Michael is right mil would refer to millimeters. Ron McHatton +More -----Original Message----- From: Cooper, Susan L.

I got my definition from the web (just goes to show you everything you read isn't correct). But if mil is millimeter, wouldn't 7 or 8 mil be really thick plastic??? (Just looking at my ruler) Susan A 'mil' would be a millimeter , one thousandth of a meter . A 'thou' is a thousandth of an inch , a big difference .
