In radar-related subjects and in JTIDS, a data mile is a unit of distance equal to 6,000 feet (1,829 metres; 0.9875 nautical miles; 1.136 miles). An international mile is 0.88 data mile. The speed of light is 299,792,458 metres per second (983,571,056 ft/s), or about one foot per nanosecond .
1,760 yards: On 1 July 1959, the imperial mile was standardized to an exact length in metres. This figure corresponds to 5280 feet at 25.4 millimeters per inch. 1,609.3472 (statute) mile: United States: 1893: 2022: 1,760 yards: From 1959 also called the US Survey Mile. From then, its only utility has been land survey, before it was the standard ...
Excepted [us 1] <10 mph (16 km/h) not allowed: Class 1: 10 mph (16 km/h) 15 mph (24 km/h) Much yard, branch line, short line, and industrial spur trackage falls into this category. Class 2: 25 mph (40 km/h) 30 mph (48 km/h) Branch lines, secondary main lines, many regional railroads, and some tourist operations frequently fall into this class.
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. [2] [3] [4] Historically, it was defined as the meridian arc length corresponding to one minute ( 1 / 60 of a degree) of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical miles (that is 60 minutes × 360 degrees).
Miles per hour (mph, m.p.h., MPH, or mi/h) is a British imperial and United States customary unit of speed expressing the number of miles travelled in one hour. It is used in the United Kingdom , the United States , and a number of smaller countries, most of which are UK or US territories, or have close historical ties with the UK or US.
The most extreme weather conditions unfolded in the Sierra Nevada, where the storm delivered hurricane-force winds and yards of snow. "At Palisades Tahoe Ski Area near Lake Tahoe, a 126 mph wind ...
Many people tend to walk at about 1.42 metres per second (5.1 km/h; 3.2 mph; 4.7 ft/s). [1] [2] [3] Individuals may find slower or faster speeds uncomfortable. Horses have also demonstrated normal, narrow distributions of preferred walking speed within a given gait, which suggests that the process of speed selection may follow similar patterns ...
1.15078 miles per hour (approximately), 20.25372 inches per second (approximately) 1.68781 feet per second (approximately). The length of the internationally agreed nautical mile is 1 852 m. The US adopted the international definition in 1954, having previously used the US nautical mile (1 853.248 m). [6]
