While a Mil is one-thousandth of an inch, a Micron is one-millionth of a meter. Since nearly all we sell is measured in Mils, it's good to have a sense of what we're talking about when packaging measured in Microns comes up: There are 25 microns in a mil. ...

The Latin numeral M denotes thousands. Thus, MM is the same as writing “M multiplied by M,” which is equal to “1,000 times 1,000”, which equals 1,000,000 (one million).

How to convert millimeters to meters? 1 Millimeter (mm) is equal to 0.001 meter (m). To convert millimeters to meters, multiply the millimeter value by 0.001 or divide by 1000. For example, to convert 500 mm to meters, divide 500 by 1000, that makes 0.5 meter is equal to 500 mm.

The magnification, m, is defined as the ratio of the image height to the object height, which is closely related to the ratio of the image distance to the object distance: A magnification of 1 (plus or minus) means that the image is the same size as the object.
