162 meters – height of the Ulm Minster, the tallest church building in the world; 165 meters – height of the Dushanbe Flagpole, the tallest flagpole from May 2011 to September 2014; 169 meters – height of the Washington Monument; 171 meters – height of the Jeddah Flagpole, the tallest flagpole from September 2014 to December 2021
For telescopic angles, the approximations of = = greatly simplify the trigonometry, enabling one to scale objects measured in milliradians through a telescope by a factor of 1000 for distance or height. An object 5 meters high, for example, will cover 1 mrad at 5000 meters, or 5 mrad at 1000 meters, or 25 mrad at 200 meters.
It was a development of an earlier technique of measuring road depressions manually with a ruler under a 10 feet (3.0 m) straight-edge. [ 4 ] [ 6 ] This method had later been developed by the British Department of Transport with the use of graduated wedges which were pushed under the ruler to measure the height, but remained a slow and ...
American surveyors use a decimal-based system of measurement devised by Edmund Gunter in 1620. The base unit is Gunter's chain of 66 feet (20 m) which is subdivided into 4 rods, each of 16.5 ft or 100 links of 0.66 feet. A link is abbreviated "lk", and links "lks", in old deeds and land surveys done for the government.
The HEC-RAS model calculated that the water backs up to a height of 9.21 meters at the upstream side of the sluice gate, which is the same as the manually calculated value. Normal depth was achieved at approximately 1,700 meters upstream of the gate. HEC-RAS modeled the hydraulic jump to occur 18 meters downstream of the sluice gate.
Cube – The cargo carrying capacity of a ship, measured in cubic metres or feet. There are two common types: Bale Cube (or Bale Capacity) – The space available for cargo measured in cubic metres or feet to the inside of the cargo battens, on the frames, and to the underside of the beams. It is a measurement of capacity for cargo in bales or ...
The clearance below required under bridges for the largest ships—container ships, ocean liners and cruise ships—is around 220 feet (67 m) so there are often bridges with approximately that height located in coastal cities with bays or inlets, such as New York City's Verrazzano-Narrows Bridge and San Francisco's Golden Gate Bridge.

foot; perch, used variously to measure length or area; acre and acre's breadth; furlong; mile; The best-attested of these is the perch, which varied in length from 10 to 25 feet, with the most common value (16 1 ⁄ 2 feet or 5.03 m) remaining in use until the twentieth century. [1] Later development of the English system continued in 1215 in ...
