For example, the Lyn locomotive of the Lynton and Barnstaple Railway is 7 feet 2 inches (2.18 m) wide. By comparison, several standard gauge 73 class locomotives of the NSWR , which are 9 feet 3 inches (2.82 m) wide, have been converted for use on 610 mm ( 2 ft ) cane tramways, where there are no narrow bridges, tunnels or track centres to ...
For example, on the MBTA subway system in the Greater Boston area, Blue Line platforms are 41.5 inches (1,054 mm) above top of rail (ATR), while Orange Line platforms are at 45 inches (1,143 mm), and Red Line platforms are at 49 inches (1,245 mm). [46] Bay Area Rapid Transit stations have platform heights of 39 inches (991 mm). [47]
There are anecdotal objections to the use of metric units in carpentry and the building trades, on the basis that it is easier to remember an integer number of inches plus a fraction, rather than a measurement in millimeters, [9] or that foot-inch measurements are more suitable when distances are frequently divided into halves, thirds, and ...
The development of different format image sensors in the main cameras of smartphones. Sizes are often expressed as a fraction of an inch, with a one in the numerator, and a decimal number in the denominator. For example, 1/2.5 converts to 2/5 as a simple fraction, or 0.4 as a decimal number. This "inch" system gives a result approximately 1.5 ...
The yellow line shows an example where 18 mm focal length on the 3:2 APS-C image sensor format (1.5 crop factor) is equivalent to 27 mm as the 35 mm format-equivalent focal length (27 mm = 18 mm * 1.5) and yields a vertical angle of 48 degrees.
The United States adopted the conversion factor 1 metre = 39.37 inches by an act in 1866. [30] In 1893, Mendenhall ordered the physical realization of the inch to be based on the international prototype metres numbers 21 and 27, which had been received from the CGPM , together with the previously adopted conversion factor.
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 Mount Washington Auto Road—originally the Mount Washington Carriage Road—is a 7.6-mile (12.2 km) private toll road on the east side of the mountain, rising 4,618 feet (1,408 m) from an altitude of 1,527 feet (465 m) at the bottom to 6,145 feet (1,873 m) at the top, an average gradient of 11.6%. The road was completed and opened to the ...
