**tael ***-
A chinese weight, equal to 1/12 lb avoirdepoise. The 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. The 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 the tegum product. The derived units are 1/n! of
the cubical scale. Names have not been formerly established for these, although
these are taken.

**tegmolatric**or diagonal

**tegmohedric**or rhombic

**tegmochoric**or octahedral **tennet ***-
A period of ten nights, cf
*fortnight*= 14 days.

Using the ancient sequencing, and ten modern planets, one might suppose that the days run as follows:Moon Mercury Venus Sun Mars Jupiter Saturn Uranus Neptune Pluto Mon Sun Sat Plu Woden Tue Uranus Friya Thor Neptune ----------------------------------------------------------------- Sun Mon Tue Wed Thu Fri Sat Sun Mon Uran Tue Wed Nept Thu 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 three days long. **TFPS ***-
A twelfty system based on a close approximate to the desired
system, using rational fractions to convert from the 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 the scientific world, this is taken to be all intervals of time.

In the field of metrology, it is useful to distinguish divisions of the day from the groupings of the day into calendar units.

A precise division of the day does not infer a precise calendar and vice versa. Civilisations need a calendar to function, but can get by with 'late afternoon', while for navigation purposes, one does need units of time.

Also, it must be noted that a given system that defines a speficic time scale can work equally well under the Christian or Hindu calendars, but not at all under the Christian or Hindu clocks. **TILF ***-
An SWS scale, derived from base 20, but used with twelfty.
This is the 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, thence:

[charge] = coulomb / 240 UES MI = 14400. **TMKS ***-
A twelfty system based on simple conversions from metric,
while still retaining the 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 other systems.

The troy weight represents the weight system of the tower system. The avoirdupoise is what would happen if the tower system was allowed to evolve.

The units are extremely close to the Prussian system. The foot is very close to the half-ell of 2.125 prussian feet, and the pound is very close to the prussian pound, close enough to suggest a common derivation of these units, eg through the Hansiatic League.length inch

A set of units or conventions designed to facilitate trade between countries
using divers measures.

Guild Units are units notionally the same size, but the precise implementation of the unit varies from country to country. For example, the Apothecaries weights are meant to replicate a system of weights found in Medicine books of the time, but the size of the ounce varies from country to country.

Pidgin Units are units of local denominations defined in terms of units of a foreign power. Although typically associated with colonial powers, the thing can arise quite naturally. Its association with colonial powers is more the same technological differences that allowed colonisation in the first place.

Import-Units are foreign denominations, originally used for the import of goods, eventually the denomination itself is imported into the system. Unlike guild or pidgin weights these become part of the native system. **Troy Weights ***-
A series of weights formerly used amongst Jewelers. While the sizes of the
units resemble those formerly used at the Troyes in France (where important
trade fairs were held), the actual size of the domination is defined in
terms of the local standard.

Since the local standard was formerly crafted by the Jewelers, the units were often constructed to be a measure of troy weights.

Until the fire of 1834, the imperial standard was 2 lb troy (11520 gt), but the standard constructed after was 7000 gt.pound 12 ounces 5760 gt ounce 20 pennyweight 480 gt pennyweight 24 grains 24 gt grain - 1 gt

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
( , formerly used in pre-Christian northern Europe.*dec:*120) **twelfty-time ***-
In practical applications, the division of the day for use with the
twelfty-system is to divide it as follows. Note that the second system
is not in general use, the main application being the time system of the
TILF system.

day \ 12 hours \ 120 minutes \ 120 seconds \ 120 thirds

day \ 120 bells \ 120 while \ 120 facc

The circle and higher spheres are divided into straight powers of 120, as follows. My first calculations in 4d was to show that the solid angle of the 600choron {3,3,5} was33s 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

The nautical units based on the twelfty-system are related to the formula of one mile per minute, as follows

earth circle \ 14400 mrinal \ 120 segments ( \ 75 geographic feet)
