    The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10 −2 metres (⁠ 1 / 100 ⁠ m = 0.01 m). To help compare different orders of magnitude , this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm).

  3. Hawaiian scale - Wikipedia

    en.wikipedia.org/wiki/Hawaiian_scale

    The expression, always given in feet, is a scaled figure corresponding to roughly half the actual measured or estimated height of a wave's face (trough to crest height). Thus, a "3-foot" wave is roughly six feet high (in actuality a height of ~1.8 m), i.e., head-high to a 6-foot (~180 cm) person; a "2-foot" wave is roughly four feet high ...

    By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.

    en.wikipedia.org/wiki/Shaku_(unit)

    Shaku (Japanese: 尺) or Japanese foot [1] [2] is a Japanese unit of length derived (but varying) from the Chinese chi, originally based upon the distance measured by a human hand from the tip of the thumb to the tip of the forefinger [3] [a] (compare span). Traditionally, the length varied by location or use, but it is now standardized as 10/ ...

    The recent formula used by the Brannock device assumes a foot length of 2 barleycorns less than the length of the last; thus, men's size 1 is equivalent to a last's length of 8 + 1 ⁄ 3 in (21.17 cm) and foot's length of 7 + 2 ⁄ 3 in (19.47 cm), and children's size 1 is equivalent to 4 + 1 ⁄ 4 in (10.8 cm) last's length and 3 + 7 ⁄ 12 in ...
