  2. Tape correction (surveying) - Wikipedia

    en.wikipedia.org/wiki/Tape_correction_(surveying)

    L= Inclined length measured A= Inclined angle When distances are measured along the slope, the equivalent horizontal distance may be determined by applying a slope correction. The vertical slope angle of the length measured must be measured. (Refer to the figure on the other side) Thus, For gentle slopes, < %

  3. Fill line - Wikipedia

    en.wikipedia.org/wiki/Fill_line

    The fill line is accompanied by the manufacturer (Sahm), the volume (0.3 litres), a CE marking, year (2014), and a code indicating the supervising body (1383). Each of the European Union member states had a variety of weights and measures acts regarding legal metrology for all measuring devices used in commerce, including drinkware .

  4. Distance from a point to a line - Wikipedia

    en.wikipedia.org/.../Distance_from_a_point_to_a_line

    The distance from (x 0, y 0) to this line is measured along a vertical line segment of length |y 0 - (-c/b)| = |by 0 + c| / |b| in accordance with the formula. Similarly, for vertical lines (b = 0) the distance between the same point and the line is |ax 0 + c| / |a|, as measured along a horizontal line segment.

  5. Track spacing - Wikipedia

    en.wikipedia.org/wiki/Track_spacing

    The European Berne Gauge has a width of 3,150 mm (10 ft 4 in). The minimal distance to structures on the side of the track is half of it but that is doubled again for double track lines. As the carriage can sway and bounce within the rail gauge, one adds 100 mm (3.9 in) and with a possible displacement of tracks over time one adds some 250 mm ...

  6. Film perforations - Wikipedia

    en.wikipedia.org/wiki/Film_perforations

    For 35 mm film these are 0.1866" and 0.1870" (4.740 mm and 4.750 mm); for 16 mm film they are 0.2994" and 0.3000" (7.605 mm and 7.620 mm). This distinction arose because early nitrocellulose film base naturally shrank about 0.3% in processing due to heat, so film printing equipment was designed to account for a size difference between its ...

    2.515 Mm – length of Norway's total land boundaries; 3.690 Mm – length of the Volga river, longest in Europe; 4.000 Mm – length of the Kalahari Desert; 4.350 Mm – length of the Yellow River; 4.600 Mm – width of the Mediterranean Sea; 4.800 Mm – length of the Sahara; 4.800 Mm – widest width of Atlantic Ocean (U.S.-Northern Africa)

  8. Graduation (scale) - Wikipedia

    en.wikipedia.org/wiki/Graduation_(scale)

    A ruler with two linear scales: the metric and imperial.It includes shorter minor graduations and longer major graduations. A graduation is a marking used to indicate points on a visual scale, which can be present on a container, a measuring device, or the axes of a line plot, usually one of many along a line or curve, each in the form of short line segments perpendicular to the line or curve.

  9. Point (typography) - Wikipedia

    en.wikipedia.org/wiki/Point_(typography)

    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 ...
