    Derived from the used of 10 yards to 1 inch. Works well with 5mm miniatures where a 6' man equals 5.08 mm 1:350: 0.871 mm: Ship models: Though assumed to be a Japanese size for ship models, its origin lies in the UK, with the release of the 1:350 Javelin and Tribal Destroyer kit in December 1945 in the FROG Penguin range.

    The standard railway track gauge, fixed at 4 feet 8 + 1 ⁄ 2 inches (1,435.1 mm) in 1845, [94] was redefined as 1,435 mm [95] – a nominal decrease of 0.1 mm but within the engineering tolerances. Motorway marker posts used by road maintenance teams and emergency services demarcate locations in multiples of 100 m. [96]

    [33] [84] The greater adjutant and marabou nearly equal the Andean condor in maximum wingspan, with all three birds believed to reach or exceed a wingspan of 3.16 m (10.4 ft). [44] Standing up to 1.53 m (5.0 ft), with a wingspan of up to 2.3 m (7.5 ft) and a weight up to 5 kg (11 lb), the African goliath heron ( Ardea goliath ) is the largest ...

    In fashion and clothing, a petite size is a standard clothing size designed specifically for women 163 cm (5 ft 4 in) and under. [1] [2] [3] This categorization is not solely based on a woman's height, but also takes into account the proportions of her body. Petite sizes cater to body shapes that typically have shorter limb lengths, narrower ...

    HO or H0 is a rail transport modelling scale using a 1:87 scale (3.5 mm to 1 foot). It is the most popular scale of model railway in the world. [1] [2] The rails are spaced 16.5 millimetres (0.650 in) apart for modelling 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge tracks and trains in HO.

  9. Minute and second of arc - Wikipedia

    en.wikipedia.org/wiki/Minute_and_second_of_arc

    The physical group size equivalent to m minutes of arc can be calculated as follows: group size = tan(⁠ m / 60 ⁠) × distance. In the example previously given, for 1 minute of arc, and substituting 3,600 inches for 100 yards, 3,600 tan(⁠ 1 / 60 ⁠) ≈ 1.047 inches. In metric units 1 MOA at 100 metres ≈ 2.908 centimetres.
