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 ...
The US survey foot is defined so that 1 metre is exactly 39.37 inches, making the international foot of 0.3048 metres exactly two parts per million shorter. This is a difference of just over 3.2 mm, or a little more than one-eighth of an inch per mile.
The former Weights and Measures office in Seven Sisters, London (590 Seven Sisters Road). The imperial system of units, imperial system or imperial units (also known as British Imperial [1] or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments.
Under the Harappan linear measures, Indus cities during the Bronze Age used a foot of 13.2 inches (335 mm) and a cubit of 20.8 inches (528 mm). [11] The Egyptian equivalent of the foot—a measure of four palms or 16 digits—was known as the djeser and has been reconstructed as about 30 cm (11.8 in).
The French National Print Office adopted a point of 2 ⁄ 5 mm or 0.400 mm in about 1810 and continues to use this measurement today (though "recalibrated" to 0.398 77 mm). [ 21 ] [ 22 ] [ 23 ] Japanese [ 24 ] and German [ 9 ] [ 16 ] [ 18 ] standardization bodies instead opted for a metric typographic base measure of exactly 1 ⁄ 4 mm or 0.250 ...
In the United States, the marking is usually in customary units (three feet 3 + 3 ⁄ 8 inches with inch and fractional inch). Hybrid measures bearing customary markings on one side and metric units on the other also exist and are sometimes referred to as yardsticks, metre-whesticks [citation needed] or "metre rulers". The spelling meter vs ...
1.0 mm – 0.03937 inches or 5/127 (exactly) 1.0 mm – side of a square of area 1 mm²; 1.0 mm – diameter of a pinhead; 1.5 mm – average length of a flea [27] 2.54 mm – distance between pins on old dual in-line package (DIP) electronic components; 5 mm – length of an average red ant; 5 mm – diameter of an average grain of rice
The pica is a typographic unit of measure corresponding to approximately 1 ⁄ 6 of an inch, or from 1 ⁄ 68 to 1 ⁄ 73 of a foot. One pica is further divided into 12 points. In printing, three pica measures are used: The French pica of 12 Didot points (also called cicero) generally is: 12 × 0.376 = 4.512 mm (0.1776 in).
