The Eley-Kynoch 9×57 cartridge manufactured by the company at its Birmingham, England factory up to the 1950s used fully jacketed and soft-nosed, round-nosed, flat-based bullets weighing 16.1 grams (248 gr), with an average muzzle velocity of 690 m/s (2,300 ft/s). Factory-loaded ammunition is now increasingly hard to come by, and most users ...
Stones of 19 millimetres (0.75 in), 25 millimetres (1.0 in) and 44 millimetres (1.75 in) are the most frequently reported hail sizes in North America. [79] Hailstones can grow to 15 centimetres (6 in) and weigh more than 0.5 kilograms (1.1 lb). [ 80 ]
Earth's orbit (Sidereal year): The Hindu cosmological time cycles explained in the Surya Siddhanta (c.600 CE), give the average length of the sidereal year (the length of the Earth's revolution around the Sun) as 365.2563627 days, which is only a negligible 1.4 seconds longer than the modern value of 365.256363004 days.

The first molars were about the size of those of a human, 1.3 cm (0.51 in), the third were 15 cm (5.9 in) long, and the sixth were about 30 cm (12 in) long and weighed 1.8 kg (4.0 lb). The molars grew larger and contained more ridges with each replacement. [ 56 ]
A BMI of ≥ 35 kg/m 2 and experiencing obesity-related health conditions or ≥ 40 or 45 kg/m 2 is morbid obesity. A BMI of ≥ 45 or 50 kg/m 2 is super obesity . As Asian populations develop negative health consequences at a lower BMI than Caucasians , some nations have redefined obesity; Japan has defined obesity as any BMI greater than 25 ...
A stellar black hole of 1 M ☉ has a Hawking temperature of 62 nanokelvins. [142] This is far less than the 2.7 K temperature of the cosmic microwave background radiation. Stellar-mass or larger black holes receive more mass from the cosmic microwave background than they emit through Hawking radiation and thus will grow instead of shrinking ...
The typical height of an adult human is between 1.4 and 1.9 m (4 ft 7 in and 6 ft 3 in), although this varies significantly depending on sex, ethnic origin, and family bloodlines. [239] [240] Body size is partly determined by genes and is also significantly influenced by environmental factors such as diet, exercise, and sleep patterns. [241]
Although winters are too cold for the classification, precipitation patterns resemble a mediterranean climate due to the summer precipitation minimum. The highest temperature recorded in Skagway is 92 °F or 33.3 °C in three separate years, most recently in 2019, and the lowest is −24 °F or −31.1 °C on February 2, 1947.
