nail *
A fingernail. As a sixteenth part of a foot, this becomes the name for a sixteenth measure.
      nail of a foot = digit
      nail of a yard = nail (cloth measure)
      nail of a cwt = clove (~ 7 lbs.)
Note sixteen appears to be a rounded value: eighteen seems more accurate.
Nautical Mile *
A unit invented by Gunter, representing a minute of arc of the earths surface.
      The modern definitions are as follows.
      sphere = same as earth surface: 1853.250 m
      US nautical mile, 1853.248 metres = 6080.197 feet [Clarke Spheroid]
      UK = 6080 feet, 1853.184 (would equate to 39.368676 for US value)
      UK metric = 1853.000 (metre ~ 39.373988 in)
      Metric international 1852.000
      Metric intended 1851.85185
Note that if one has a different system of angles, then this unit also changes. For exammple, the twelfty-system has 14400 minutes in the circle, giving the mrinal, while the metric system has 40000 degrees, giving the kilometre.
NewAge *
The term newage refers to the once-and-future world, of which we are living in some intermediate darkness. The great disasters that wrought the end of ancient civilisations, and some hope that the glory of these might return is the driving theme.
      Although the study is ancient, the passing of important events, such as the dawning of the age of Aquarius [ie when the first point of Aries moved into Aquarius], brought a lot of this into the attention of the general population.
      Much speculation goes onto the nature of the once and former world. But not with standing, the suggested metrologies are legitimate uses of it, and well within the scope of this survey.
      Because the metre and the new age units derive from the measurements of the earth's circumference, one might derive the 'correct' conversion of the metre in inches. Here are some examples,
Berriman 39.366 000 000 000 Based on 54 digits of 0.729 inch
Smyth 39.375 000 000 00 Polar axis = 5e8 inches + geographic pi = 3.15
Admiralty 39.398 400 000 000 Based on 3.24 feet of 12.16 inches
Neal 39.414 988 800 000 Based on an earth sphere of 24883.2 miles.
Nines *
A measurement system constructed by setting various constants to the ninth power of ten: viz 1,000,000,000 (twe: 4 9884 5340). This is one of my first scientific systems, and from it, comes the idea of magnetic numbers.
Length foot light nanosecond = 299.792 458 m/m
      mile (6000 feet), fathom (6 feet), inch (1/12 foot) &c.
Mass pound Defined that 1/G = 10**9 lb.s²/ft³.
this makes metric water (1000 kg/m³) into 66.73 lb/ft³.
      ton 2400 pound, cwt 120 lb, stone 15 lb, oz 1/16 lb &c..
Nines water is 66 2/3 lb/ft³.
Time second The time system is unmodified.
Charge Q Implemented by setting 10**-7 H/m to the appropriate nines unit, so in design, an UES-MI rule.
      NNA makes μ as 4πE-9 'H'/ft, [UES MI]
      NNB makes μ as 1E-9 'H'/ft [UES MR]
      NNU is the unrationalised from of it. [UES MU]
Thremm Kelvin Temperature units are not part of the nines system, it can be used without upset to its design under any thremmglass.
