The "old English mile" of the medieval and early modern periods varied but seems to have measured about 1.3 international miles (2.1 km). [17] [18] The old English mile varied over time and location within England. [18] The old English mile has also been defined as 79,200 or 79,320 inches (1.25 or 1.2519 statute miles). [19]
(Some people have claimed there are six more 8,000m peaks in Nepal, making for a total of 20. [1]) All are in the two highest mountain ranges in the world, the Himalayas and the Karakoram . Mount Everest - 8,848 m (29,029 ft) K2 - 8,611 m (28,251 ft) Kanchenjunga - 8,586 m (28,169 ft)
This list ranks completed and topped-out buildings in the United States that stand at least 800 feet (244 m) tall, based on standard height measurement which includes spires and architectural details, but excludes antenna masts. An equal sign (=) following a rank indicates the same height between two or more buildings.
To be included on the list, a place needs to be an incorporated municipality (i.e. a city, town, or village) and it needs to be at an elevation of 3,000 feet (914 m) or higher. In the United States, settlements above 3,000 feet are found primarily on the High Plains, in the Rocky Mountains, and in Western North Carolina. However, since many ...
So, for example, if a route is 20 kilometres (12 mi) with 1600 metres of climb (as is the case on leg 1 of the Bob Graham Round, Keswick to Threlkeld), the equivalent flat distance of this route is 20+(1.6×8)=32.8 kilometres (20.4 mi). Assuming an individual can maintain a speed on the flat of 5 km/h, the route will take 6 hours and 34 minutes.
The falls are usually flowing year-round and the lower falls are reached via a popular, approximately 3 ⁄ 4 mile (1,200 m) hike (each way). The first 1 ⁄ 2 mile (800 m) follows the South Fork Lytle Creek wash to a side trail that takes you approximately 1 ⁄ 4 mile (400 m) to the base of the falls. The trailhead for the falls is an ...

Pressure as a function of the height above the sea level. The human body can perform best at sea level, [7] where the atmospheric pressure is 101,325 Pa or 1013.25 millibars (or 1 atm, by definition). The concentration of oxygen (O 2) in sea-level air is 20.9%, so the partial pressure of O 2 (pO 2) is 21.136 kilopascals (158.53 mmHg).
