  2. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    The micrometre (SI symbol: μm) is a unit of length in the metric system equal to 10 −6 metres (⁠ 1 / 1 000 000 ⁠ m = 0. 000 001 m). To help compare different orders of magnitude , this section lists some items with lengths between 10 −6 and 10 −5 m (between 1 and 10 micrometers , or μm).

  3. Aspect ratio - Wikipedia

    en.wikipedia.org/wiki/Aspect_ratio

    For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, [1] [2] when the rectangle is oriented as a "landscape". The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal fraction. The values x and y do ...

  4. Display size - Wikipedia

    en.wikipedia.org/wiki/Display_size

    When the common aspect ratio shifted from 4:3 to 16:9, the new widescreens were labeled with a W in the US. A screen that is approximately the same height as a 27V would be a 32W. Vizio and other US TV manufacturers have introduced even wider screens with a 21:9 aspect ratio to match aspect ratios used in cinemas. To gauge the relative sizes of ...

  5. Aspect ratio (image) - Wikipedia

    en.wikipedia.org/wiki/Aspect_ratio_(image)

    Cinerama at full height (three specially captured 35 mm images projected side by side into one composite widescreen image). 2. 6:1 = 8:3 = 24:9 Full-frame output from Super 16 mm negative when an anamorphic lens system has been used. Effectively, an image that is of the ratio 24:9 is squashed onto the native 15:9 aspect ratio of a Super 16 mm ...

    The Degree (D) value has an almost linear dependence on the square root of the average wave Height (H) above, i.e., +. Using linear regression on the table above, the coefficients can be calculated for the low Height values ( λ L = 2.3236 , β L = 1.2551 {\textstyle \lambda _{L}=2.3236,\beta _{L}=1.2551} ) and for the high Height values ( λ H ...

  7. Display resolution standards - Wikipedia

    en.wikipedia.org/wiki/Display_resolution_standards

    Certain combinations of width and height are standardized (e.g. by VESA [1] [2]) and typically given a name and an initialism which is descriptive of its dimensions. The graphics display resolution is also known as the display mode or the video mode, although these terms usually include further specifications such as the image refresh rate and ...

  8. Human height - Wikipedia

    en.wikipedia.org/wiki/Human_height

    Height measurement using a stadiometer. Human height or stature is the distance from the bottom of the feet to the top of the head in a human body, standing erect.It is measured using a stadiometer, [1] in centimetres when using the metric system or SI system, [2] [3] or feet and inches when using United States customary units or the imperial system.

  9. Mars Climate Orbiter - Wikipedia

    en.wikipedia.org/wiki/Mars_Climate_Orbiter

    The Mars Climate Orbiter bus measured 2.1 meters (6 feet 11 inches) tall, 1.6 meters (5 feet 3 inches) wide and 2 meters (6 feet 7 inches) deep. The internal structure was largely constructed with graphite composite/aluminum honeycomb supports, a design found in many commercial airplanes .
