1.6 × 10 −5 quectometers (1.6 × 10 −35 meters) – the Planck length (Measures of distance shorter than this do not make physical sense, according to current theories of physics.) 1 qm – 1 quectometer, the smallest named subdivision of the meter in the SI base unit of length, one nonillionth of a meter.
A seismogram recorded in Massachusetts, United States. The magnitude 9.1 (M w) undersea megathrust earthquake occurred on 11 March 2011 at 14:46 JST (05:46 UTC) in the north-western Pacific Ocean at a relatively shallow depth of 32 km (20 mi), [9] [56] with its epicenter approximately 72 km (45 mi) east of the Oshika Peninsula of Tōhoku, Japan, lasting approximately six minutes.
If using the metric unit meters for distance and the imperial unit inches for target size, one has to multiply by a factor of 25.4, since one inch is defined as 25.4 millimeters. distance in meters = target in inches angle in mrad × 25.4 {\displaystyle {\text{distance in meters}}={\frac {\text{target in inches}}{\text{angle in mrad}}}\times 25.4}
Suffered many bone fractures. [1] [2] [3] Luke Aikins: 25,000 [4] 7,620 2016 On July 30, 2016, Aikins jumped from an aircraft without any parachute or wingsuit at an altitude of 25,000 feet (7,620 m) above Simi Valley, California, watched by a live audience. After about two minutes of free fall he successfully landed in a 100-by-100-foot (30 by ...
A magnitude 8.3 to 8.4 earthquake in the Pacific Ocean off Iturup in the Kuril Islands on 6 November 1958 generated a tsunami with a height of up to 5 metres (16 ft) at Shikotan, 2 to 4 metres (7 to 13 ft) at Iturup, and up to 2 metres (6.6 ft) in northern Hokkaido, Japan.
Posidonius calculated the Earth's circumference by reference to the position of the star Canopus.As explained by Cleomedes, Posidonius observed Canopus on but never above the horizon at Rhodes, while at Alexandria he saw it ascend as far as 7 + 1 ⁄ 2 degrees above the horizon (the meridian arc between the latitude of the two locales is actually 5 degrees 14 minutes).
Height measurement using a stadiometer. Human height or stature is the distance from the bottom of the feet to the top of the head in a human body, standing erect.It is measured using a stadiometer, [1] in centimetres when using the metric system or SI system, [2] [3] or feet and inches when using United States customary units or the imperial system.
Pace [6] in minutes per kilometre or mile vs. slope angle resulting from Naismith's rule [7] for basal speeds of 5 and 4 km / h. [n 1]The original Naismith's rule from 1892 says that one should allow one hour per three miles on the map and an additional hour per 2000 feet of ascent.
