  2. String girdling Earth - Wikipedia

    en.wikipedia.org/wiki/String_girdling_Earth

    Surprisingly, the answer is 2 π m or around 6.3 metres (21 ft). In the second phrasing, considering that 1 metre (3 ft 3 in) is almost negligible compared with the 40,000 km (25,000 mi) circumference, the first response may be that the new position of the string will be no different from the original surface-hugging position.

  3. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    Leonardo da Vinci drew the Vitruvian Man within a square of side 1.83 m (6 ft 0 in) and a circle about 1.2 m (3 ft 11 in) in radius. To help compare different orders of magnitude, this section lists lengths between one meter and ten meters. Light, in vacuum, travels 1 meter in 1 ⁄ 299,792,458, or 3.3356409519815E-9 of a second.

    Its dried skin plus head measured 6.2 m (20 ft 4 in) in length and it was estimated to have been 6.3 m (20 ft 8 in) when accounting for shrinkage and a missing tail tip. [ 9 ] [ 8 ] Projected from their skull lengths, multiple specimens from Singapore were estimated to belong in life to male crocodiles measuring more than 6 m (19 ft 8 in). [ 48 ]

  5. 9.3×62mm - Wikipedia

    en.wikipedia.org/wiki/9.3×62mm

    The 9.3×62mm was first loaded with an 18.5 grams (285 gr) bullet at a muzzle velocity of 655 m/s (2,150 ft/s). After World War I some companies increased the velocity to around 730 m/s (2,400 ft/s), and brought out lighter bullets. Rifles set up for the original load have their sights readjusted to shoot the newer load to point of aim.

    en.wikipedia.org/wiki/Intermodal_container

    Standard containers are 8 feet (2.44 m) wide by 8 ft 6 in (2.59 m) high, [nb 6] although the taller "High Cube" or "hi-cube" units measuring 9 feet 6 inches (2.90 m) have become very common in recent years [when?]. By the end of 2013, high-cube 40 ft containers represented almost 50% of the world's maritime container fleet, according to Drewry ...
