A circular mil is a unit of area, equal to the area of a circle with a diameter of one mil (one thousandth of an inch or 0.0254 mm). It corresponds to approximately 5.067 × 10−4 mm2. It is a unit intended for referring to the area of a wire with a circular cross section. As the definition of the unit contains π, it is easy to calculate area ...
A thousandth of an inch is a derived unit of length in a system of units using inches. Equal to 1000 of an inch, a thousandth is commonly called a thou / ˈθaʊ / (used for both singular and plural) or, particularly in North America, a mil (plural mils). The words are shortened forms of the English and Latin words for "thousand" (mille in Latin).
Hegman gauge. A Hegman gauge, sometimes referred to as a grind gauge, grind gage, or grindometer, is an instrument which indicates the fineness of grind or the presence of coarse particles and agglomeration in a dispersion. [1] It is commonly used to determine how finely ground the particles of pigment (or other solid) dispersed in a sample of ...
The micrometre (Commonwealth English as used by the International Bureau of Weights and Measures; [1] SI symbol: μm) or micrometer (American English), also commonly known by the non-SI term micron, [2] is a unit of length in the International System of Units (SI) equalling 1 × 10 −6 metre (SI standard prefix "micro-" = 10 −6); that is, one millionth of a metre (or one thousandth of a ...
Thickness of aluminum foil is measured in mils (1 ⁄ 1000 inch, or 0.0254 mm) in the United States. Cross-sectional area of electrical wire is measured in circular mils in the U.S. and Canada, one circular mil (cmil) being equal to 5.067 × 10 −4 mm 2 (or 7.854 × 10 −7 in 2). Since this is so small, actual wire is commonly measured in ...
A ris is 2 ⁄ 15, or about 0.13, of a mil. According to Rashi (Baba Kama 79b, s.v. שלושים ריס), thirty ris is equivalent to 4 mil. Maimonides concurs in his commentary on Mishnah yoma 6:4, where 90 ris is put at 12 mil. Mil (Milin) mile: 0.598–0.712 mi (in case of Talmud opinion referencing a Roman mile: 0.919 mi [12] [13])
Metric prefix. A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic. Each prefix has a unique symbol that is prepended to any unit symbol. The prefix kilo-, for example, may be added to gram to indicate multiplication by one thousand ...
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property ...
