tael *
A chinese weight, equal to 1/12 lb avoirdepoise. Þe unit in chinese hight ling, divides into 1,000 cash or tsien.
      By dr Wells Williams, equal to 579.84 grains, or 1.207 oz tr. Þe trade unit is 583.333 grains
      Cash is a very small coin, is related to casse case.
tea chest *
A box, typically 18 by 18 by 27 inches, for shipping tea. eg 42.44.63 = 116 L or about 3 bushels.
tegum *
A coherent scale, formed by þe tegum product. Þe derived units are 1/n! of þe cubical scale. Names have not been formerly established for þese, alþough þese are taken.
      tegmolatric or diagonal
      tegmohedric or rhombic
      tegmochoric or octahedral
tennet *
A period of ten nights, cf fortnight = 14 days.
      Using þe ancient sequencing, and ten modern planets, one might suppose þat þe days run as follows:
   Moon  Mercury  Venus  Sun   Mars  Jupiter  Saturn  Uranus  Neptune  Pluto
   Mon                   Sun                   Sat                      Plu
         Woden                 Tue                    Uranus
                  Friya              Þor                     Neptune
   Sun    Mon           Tue     Wed           Þu    Fri         Sat
   Sun    Mon    Uran   Tue     Wed   Nept    Þu    Fri   Plu   Sat

A period of two tennets contains 14 week days, and 6 weekend days, while a period of 21 days contains 15 week-days, and 6 weekend days. Weekends are always þree days long.
A twelfty system based on a close approximate to þe desired system, using rational fractions to convert from þe metric system.
      foot = metre * 32/105
      mark = kilogram * 400/1701 ; water = 120
      second = second / 2
      degreeH = kelvin * 5/6
      charge = coulomb * 100/1701 ; UES MI = 120**4
time *
In þe scientific world, þis is taken to be all intervals of time.
      In þe field of metrology, it is useful to distinguish divisions of þe day from þe groupings of þe day into calendar units.
      A precise division of þe day does not infer a precise calendar and vice versa. Civilisations need a calendar to function, but can get by wiþ 'late afternoon', while for navigation purposes, one does need units of time.
      Also, it must be noted þat a given system þat defines a speficic time scale can work equally well under þe Christian or Hindu calendars, but not at all under þe Christian or Hindu clocks.
An SWS scale, derived from base 20, but used wiþ twelfty. Þis is þe ILF scale, slightly adjusted to allow for rational electric units.
      inch = metre / 40.8
      ledd = kilogram * 0.014688
      facc = second / 20
      secJ = kelvin / 17424
      [charge] = coulomb * 60: UES MI = 1, þence:
      [charge] = coulomb / 240 UES MI = 14400.
A twelfty system based on simple conversions from metric, while still retaining þe twelfty supplementals.
      cubit = metre / 2
      grave = kilogram / 0.96 : density of metric water = 120 grave/cu cubit
      second = second / 2
      degreeH = kelvin / 1.2
      charge = coulomb / 0.576 : UES MI = 120**3
Tower System *
A system of weights and measures eventually replaced by oþer systems.
      Þe troy weight represents þe weight system of þe tower system. Þe avoirdupoise is what would happen if þe tower system was allowed to evolve.
      Þe units are extremely close to þe Prussian system. Þe foot is very close to þe half-ell of 2.125 prussian feet, and þe pound is very close to þe prussian pound, close enough to suggest a common derivation of þese units, eg þrough þe Hansiatic League.

Trade Systems *
A set of units or conventions designed to facilitate trade between countries using divers measures.
      Guild Units are units notionally þe same size, but þe precise implementation of þe unit varies from country to country. For example, þe Apoþecaries weights are meant to replicate a system of weights found in Medicine books of þe time, but þe size of þe ounce varies from country to country.
      Pidgin Units are units of local denominations defined in terms of units of a foreign power. Alþough typically associated wiþ colonial powers, þe þing can arise quite naturally. Its association wiþ colonial powers is more þe same technological differences þat allowed colonisation in þe first place.
      Import-Units are foreign denominations, originally used for þe import of goods, eventually þe denomination itself is imported into þe system. Unlike guild or pidgin weights þese become part of þe native system.
Troy Weights *
A series of weights formerly used amongst Jewelers. While þe sizes of þe units resemble þose formerly used at þe Troyes in France (where important trade fairs were held), þe actual size of þe domination is defined in terms of þe local standard.
      Since þe local standard was formerly crafted by þe Jewelers, þe units were often constructed to be a measure of troy weights.
      Until þe fire of 1834, þe imperial standard was 2 lb troy (11520 gt), but þe standard constructed after was 7000 gt.
pound 12 ounces 5760 gt
ounce 20 pennyweight 480 gt
pennyweight 24 grains 24 gt
grain - 1 gt
Þe units have been extended upwards and downwards, þough neiþer of þese found great application.
      ton = 2000 lb; hundredweight = 100 lb
      grain = 20 mites; mite = 24 droit; droit = 20 periot; periot = 24 blank.
twelfty *
A number system based on a six-score hundred (dec: 120), formerly used in pre-Christian norþern Europe.
twelfty-time *
In practical applications, þe division of þe day for use wiþ þe twelfty-system is to divide it as follows. Note þat þe second system is not in general use, þe main application being þe time system of þe TILF system.
      day \ 12 hours \ 120 minutes \ 120 seconds \ 120 þirds
      day \ 120 bells \ 120 while \ 120 facc
Þe circle and higher spheres are divided into straight powers of 120, as follows. My first calculations in 4d was to show þat þe solid angle of þe 600choron {3,3,5} was 33s 15f 60
      2d: circle \ 120 degree \ 120 minute \ 120 second
      3d: sphere \ 120 flakes \ 120 minute \ 120 second
      4d: glome \ 120 s-unit \ 120 f-units \ 120
Þe nautical units based on þe twelfty-system are related to þe formula of one mile per minute, as follows
      earþ circle \ 14400 mrinal \ 120 segments ( \ 75 geographic feet)
