Referring to phenomena of mass as gravitation. Mechanics generally treats of molar laws and phenomena. [Transcriber's note: Molar, or mole, often refers to a quantity of a substance containing an Avagadro number (6.02E23) of molecules--a weight equal to the atomic weight of the molecule. For example, a mole of hydrogen (H2) is 2.015 grams; sodium [...]

Contraction for millimeters.

A proposed but not adopted unit of current; one-thousandth of an oerstedt. It is equal to one-thousandth of an ampere. [Transcriber's note: oersted: 1. CGS unit of magnetic intensity, equal to the magnetic pole of unit strength when undergoing a force of one dyne in a vacuum. 2. Formerly, the unit of magnetic reluctance equal [...]

A unit of length; one-thousandth of a meter. It is equal to 39.37079 mils; .03937 inch; .00109 yard.

A unit of weight ; one-thousandth of a gram, q. v. It is equal to .015432 grain; .000032 troy ounce.

A prefix; one-thousandth. Thus a milligram is one-thousandth of a gram; a millimeter is one thousandth of a meter.

A unit of area; one-millionth of a square inch. It is equal to .000645 square millimeter; 1.2733 circular mil; .000001 square inch.

A unit of area; employed in designating the cross-sectional area of wires and other circular conductors. It is equal to .78540  square mil; .000507 square millimeter; 7.8E-7 (.00000078) square inch. If the diameter of a wire is given in mils, the square of its diameter gives its cross-sectional area in circular mils.

A unit of resistance. (See Resistance, Mil-foot, Unit of).

A unit of length; one-thousandth part of a lineal inch. It is equal to .025399 millimeter; .000083 foot; .001000 inch.
