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

    The millimetre (SI symbol: mm) is a unit of length in the metric system equal to 10 −3 metres (⁠ 1 / 1 000 ⁠ m = 0.001 m). To help compare different orders of magnitude, this section lists lengths between 10 −3 m and 10 −2 m (1 mm and 1 cm). 1.0 mm – 1/1,000 of a meter; 1.0 mm – 0.03937 inches or 5/127 (exactly)

    In most US cities, a city block is between 1 ⁄ 16 and 1 ⁄ 8 mi (100 and 200 m). In Manhattan, the measurement "block" usually refers to a north–south block, which is 1 ⁄ 20 mi (80 m). Sometimes people living in places (like Manhattan) with a regularly spaced street grid will speak of long blocks and short blocks.

    In the twentieth century in the Republic of China, the lengths were standardized to fit with the metric system, and in current usage in People's Republic of China and Taiwan [citation needed] it measures ⁠3 + 1 / 3 ⁠ cm (~1.312 in). In Japan, the corresponding unit, sun (寸), was standardized at 1000 ⁄ 33 mm (3. 03 cm, ~1.193 in, or ~0. ...

    A centimetre of water [1] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 cmH 2 O (4°C) = 999.9720 kg/m 3 × 9.80665 m/s 2 × 1 cm = 98.063754138 Pa ≈ 98.0638 Pa, but conventionally a nominal maximum water density of 1000 kg/m 3 is used, giving ...
