    Following the initial trials, the K-102 continued making trial launches with both the R-27 and the R-27K, until it was accepted for service on 15 August 1975. [ 6 ] Using external targeting data, the R-27K/SS-NX-13 would have been launched underwater to a range of between 350 and 400 nm (650–740 km), covering a "footprint" of 27 nm (50 km).

  5. Orders of magnitude (time) - Wikipedia

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

    Clock time and calendar time have duodecimal or sexagesimal orders of magnitude rather than decimal, e.g., a year is 12 months, and a minute is 60 seconds. The smallest meaningful increment of time is the Planck time ―the time light takes to traverse the Planck distance , many decimal orders of magnitude smaller than a second.

    Although the length of a moment in modern seconds was therefore not fixed, on average, a medieval moment corresponded to 90 seconds. A solar day can be divided into 24 hours of either equal or unequal lengths, [ 2 ] [ 3 ] the former being called natural or equinoctial, and the latter artificial.

[2] Although not a unit in the International System of Units (SI), the minute is accepted for use in the SI. [1] The SI symbol for minutes is min (without a dot). The prime symbol ′ is also sometimes used informally to denote minutes. [3]
