16 18.6 TWh The approximate radiated surface energy released in a magnitude 8 earthquake. [35] 21.5 25 TWh The complete conversion of 1 kg of matter into pure energy would yield the theoretical maximum (E = mc 2) of 89.8 petajoules, which is equivalent to 21.5 megatons of TNT. No such method of total conversion as combining 500 grams of matter ...
Potential energy with respect to gravity, close to Earth, per unit mass: gh, where g is the acceleration due to gravity (standardized as ≈9.8 m/s 2) and h is the height above the reference level (giving J/kg when g is in m/s 2 and h is in m).

The PK and 6T2 tripod weigh 16.5 kg (36.38 lb). The 6T2 Samozhenkov general-purpose tripod mount was designed by E. S. Samozhenkov and entered service in 1961 and weighs 7.5 kg (16.53 lb). The 6T2 Samozhenkov tripod mount was earlier envisioned for the Nikitin-Sokoiov machine gun that was not adopted by the Soviet Union. All types of ammunition ...
The Air Force expected to use the Space Shuttle to launch large satellites, and required it to be capable of lifting 29,000 kg (65,000 lb) to an eastward LEO or 18,000 kg (40,000 lb) into a polar orbit. The satellite designs also required that the Space Shuttle have a 4.6 by 18 m (15 by 60 ft) payload bay.
The MP 18 was a heavy weapon, weighing over 5 kg (11.0 lb) when fully loaded. The receiver tube was very thick (around 3 mm), compared with later World War II submachine guns with half that thickness or less, such as the Sten gun or MP 40.
The Soviet Union continued sending robotic missions to the Moon until 1976, deploying in 1970 with Luna 17 the first remote controlled rover Lunokhod 1 on an extraterrestrial surface, and collecting and returning 0.3 kg of rock and soil samples with three Luna sample return missions (Luna 16 in 1970, Luna 20 in 1972, and Luna 24 in 1976).

Females in any given wolf population typically weigh 5–10 lb (2.3–4.5 kg) less than males. Wolves weighing over 54 kg (119 lb) are uncommon, though exceptionally large individuals have been recorded in Alaska and Canada. [47] In central Russia, exceptionally large males can reach a weight of 69–79 kg (152–174 lb). [43]
