2. United States customary units - Wikipedia

   en.wikipedia.org/wiki/United_States_customary_units

   For measuring length, the U.S. customary system uses the inch, foot, yard, and mile, which are the only four customary length measurements in everyday use. From 1893, the foot was legally defined as exactly 1200 ⁄ 3937 m (approximately 0.304 8006 m). [13] Since July 1, 1959, the units of length have been defined on the basis of 1 yd = 0.9144 ...

3. Foot (unit) - Wikipedia

   In many cases the length of the unit was not uniquely fixed: for example, the English foot was stated as 11 pouces 2.6 lignes (French inches and lines) by Picard, 11 pouces 3.11 lignes by Maskelyne, and 11 pouces 3 lignes by D'Alembert. [47] Most of the various feet in this list ceased to be used when the countries adopted the metric system.

   Concert grand pianos range in scale from about 7 feet 6 inches to 9 feet 0 inches (229 to 274 cm) or occasionally more. Notable concert grands include: The Steinway Model D, at 8 feet 11 + 3 ⁄ 4 inches (273.7 cm). The Imperial Bösendorfer, at 9 feet 6 inches (290 cm) with 97 keys. The Fazioli F308 at 10 feet 2 inches (310 cm).

   The sensed image, which includes the target, is displayed on a monitor, where it can be measured. Dimensions of the full image display and of the portion of the image that is the target are determined by inspection (measurements are typically in pixels, but can just as well be inches or cm). = dimension of full image

   The plate distance is one centimeter, the special conductivity values were calculated from the Lasance approximation formula in The Thermal conductivity of Air at Reduced Pressures and Length Scales [28] and the primary values were taken from Weast at the normal pressure tables in the CRC handbook on page E2. [27]

9. Image sensor format - Wikipedia

   en.wikipedia.org/wiki/Image_sensor_format

   Because the image sensors in many digital cameras are smaller than the 24 mm × 36 mm image area of full-frame 35 mm cameras, a lens of a given focal length gives a narrower field of view in such cameras. Sensor size is often expressed as optical format in inches. Other measures are also used; see table of sensor formats and sizes below.
