difference between american wire gauge and standard wire gauge
Standard wire gauge SWG was fixed by Order of Council August 23, 1883. It was constructed by improving the Birmingham Wire Gauge. It was made a legal standard on March 1, 1884 by the British Board of Trade. SWG is not to be confused with American Wire Gauge which has a similar but not quite interchangeable numbering scheme.
Flag of the United States The exact red, white, and blue colors to be used in the flag are specified with reference to the CAUS Standard Color Reference of America, 10th edition. Specifically, the colors are "White", "Old Glory Red", and "Old Glory Blue".[64] The CIE coordinates for the colors of the 9th edition of the Standard Color Card were formally specified in JOSA in 1946.[65] These colors form the standard for cloth, and there is no perfect way to convert them to RGB for display on screen or CMYK for printing. The "relative" coordinates in the following table were found by scaling the luminous reflectance relative to the flag's "white".
