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.
For example, a rifle capable of firing a ½ or 0.5 MOA (approximately 0.5 inch center to center of the two holes furthest apart) 5-round group (often referred to as "grouping") at 100 yards will theoretically fire a 12.5 inch group at 2,500 yards (0.5 × 2,500/100 = 12.5). Unless the group is centered perfectly on the target at 100 yards, the ...
Kincheloe flew 2000 miles per hour (3,200 km/h) at 126,000 feet (38,500 m), or 24 miles up. At this altitude and speed, aerodynamic lift still carries 98 percent of the weight of the plane, and only two percent is carried by inertia, or Kepler force , as space scientists call it.
Mauna Loa (4,169 m or 13,678 ft) is the largest mountain on Earth in terms of base area (about 5,200 km 2 or 2,000 sq mi) and volume (about 42,000 km 3 or 10,000 cu mi), although, due to the intergrade of lava from Kilauea, Hualalai and Mauna Kea, the volume can only be estimated based on surface area and height of the edifice.
The Irish mile (míle or míle Gaelach) measured 2,240 yards: approximately 1.27 statute miles or 2.048 kilometres. [ 39 ] [ 40 ] It was used in Ireland from the 16th century plantations until the 19th century, with residual use into the 20th century.
The South Pole-Aitken basin is believed to be the largest and oldest crater on the moon, spanning nearly a quarter of the lunar surface with a diameter measuring roughly 1,550 miles (2,500 ...
Triathlon, as defined by the International Triathlon Union, may feature running sections ranging from five kilometres (3.1 miles) to the marathon distance (42.195 kilometres, or 26 miles and 385 yards), depending on the race type. [46] The related sport of duathlon is a combination of cycling and distance running. [47]
Start with fewer miles and then increase over time to create a more sustainable routine. Aim for: anywhere between 2,000 and 8,000 steps per day—which is between one and four miles.
