Average distance between the center of Earth and the center of the Moon. astronomical unit au. Defined as 149 597 870 700 m. [16] Approximately the distance between the Earth and Sun. light-year ly ≈ 9 460 730 472 580.8 km. The distance that light travels in a vacuum in one Julian year. [17] parsec pc ≈ 30 856 775 814 671.9 km or about 3. ...
The basic Chinese traditional unit of distance was the chi. As its value changed over time, so did the li ' s. In addition, the number of chi per li was sometimes altered. To add further complexity, under the Qin dynasty, the li was set at 360 "paces" (步, bù) but the number of chi per bu was subsequently changed from 6 to 5, shortening the ...
The French lieue — at different times — existed in several variants, namely 10,000, 12,000, 13,200 and 14,400 French feet, about 3.25 to 4.68 km (2.02 to 2.91 miles). It was used along with the metric system for a while, but is long discontinued.
Usually, transport risk is computed by reference to the distance traveled by people, while for road traffic risk, only vehicle traveled distance is usually taken into account. [7] In the United States, the unit is used as an aggregate in yearly federal publications, while its usage is more sporadic in other countries.
A value in decimal degrees to 5 decimal places is precise to 1.11 metres (3 ft 8 in) at the equator. Elevation also introduces a small error: at 6,378 metres (20,925 ft) elevation, the radius and surface distance is increased by 0.001 or 0.1%.
[25] [26] The standard FIFA football pitch for international matches is 105 m (344 ft) long by 68 m (223 ft) wide (7,140 m 2 or 0.714 ha or 1.76 acres); FIFA allows for a variance of up to 5 m (16.4 ft) in length in either direction and 7 m (23.0 ft) more or 4 m (13.1 ft) less in width (and larger departures if the pitch is not used for ...
