I am bit confused, I see in some papers they use like 20 mils is it equal to
can any one clarify this

in electronics it's not the same: mils = milli inch, so 20 mils = 0.508mm; 20mm = 787.402mil
on the other hand i found these definitions for "mil": http://en.wikipedia.org/wiki/Mil
A mil is an abbreviation or colloquial abbreviation for different units
- one thousandth of an inch (one thou), often used for specifying the thickness of films and sheets
- millimetre, one thousandth of a metre
- millilitre, a unit of volume
- milliradian, a thousandth of a radian, a unit of angle
- a million

what is mils unit
No, it is not millimeter. It is milli-inch.
1 mil equals 0.001 inch.
Also, "thou" is used to denote 0.001 inch. 1 thou (1th) equals 0.001 inch.

Hope will be clear by this
a unit of distance equal to 0.001 inch: a "milli-inch," in other words. Mils are used, primarily in the U.S., to express small distances and tolerances in engineering work. One mil is exactly 25.4 microns, just as one inch is exactly 25.4 millimeters. This unit is also called the thou. With the increasing use of metric units in the U.S., many machinists now avoid the use of "mil" because that term is also a handy slang for the millimeter.
a unit of angle measure, used in the military for artillery settings.
a common slang name for the milliliter (mL) or the millimeter (mm).
in Scandinavia, the mil, pronounced like "meal" in English, is a traditional distance unit considerably longer than Roman or English miles.
an alternate spelling of the mill  (see below).
mile (mi) 
a traditional unit of distance. The word comes from the Latin word for 1000, mille, because originally a mile was the distance a Roman legion could march in 1000 paces (or 2000 steps, a pace being the distance between successive falls of the same foot). T

mile per gallon (mi/gal or mpg)
the unit customarily used in the United States to measure the fuel efficiency of motor vehicles. 1 mile per gallon equals about 0.4252 kilometers per liter.
mile per hour (mi/h or mph)
a traditional unit of velocity. One mile per hour equals exactly 22/15 feet per second, approximately 1.609 kilometers per hour (km/h), or exactly 0.447 04 meter per second (m/s).
a mil-foot is a section of wire one foot long and one mil in diameter; this would be a unit of volume equal to about 0.0377 cubic inches or 0.6178 cubic centimeters.
the traditional Portuguese mile, one of the "longest miles" of all at 2282.75 yards (1.297 statute miles or 2087.3 meters).
another name for a step. In the U.S. Army, the military pace is defined to be exactly 30 inches (76.2 centimeters) for ordinary "quick time" marching and 36 inches (91.44 centimeters) for double time marching. The same definitions are generally used by marching bands.
an informal unit of quantity or of proportion, equal to 0.001. When Congress established the U. S. monetary system in 1791, it provided for 10 mills to the cent and 100 cents to the dollar; thus the mill was an amount of money equal to $0.001.
