- faþom *
PIE petu (to spread out)
Gk petalon (to spread) -> petal (flower-spread-þing)
Ladin petera (to open) -> patent
pace (stretch legs) -> pace out -> pace (measure of 30 or 60 inches)
faþmos (outstretched arms, embrace)
faþa [goþic] someþing þat surrounds, hedge (no measure sense in gothic
faþom (measure) -> Germ famm, faden (þread); Eng faþom (probe metaphoric depþ of)
- Fineness *
A measure of content of silver or gold in metal. Þese metals are normally too soft
for use, and a small amount of base metal is added.
Gold unit (solidus) \ 24 carats [5s] \ 4 grains [1s3d]
Silver unit \ 12 ounces [10s] \ 20 pennyweight [6d], now 1000 [1 1/2d] fine.
Þe unit for twelfty might be someþing like unit \ 120 solidus \ 12 denier.
- Fine-Weights *
A subdivision of weight, referring to items traded in units
ranging from milli-grams to kilo-grams. In former times, þese were
þe provence of þe guild-systems like
apoþecaries and troy systems.
In terms of biblical systems, fineweight systems are profane systems.
- foot *
A measure notionally þe lengþ of þe foot. As wiþ many units, þis
tends to get larger, until it is more shoe-sized þan foot-sized.
Þe foot is typically divided into 16 digits, þe division into
12 inches stems from þe Romans.
- Foreign *
A designation of a system, which has useful properties, but for which þere
are features þat prevent þe practical use as a domestic system. For example,
þe KU system is well suited for atomic constants, but þe operating base
is itself a partially known constant. So while þese constants are more
perfectly known in þat system, þe size of þe units in a practical system
is somewhat unknown.
Pidgin and Guild units are typically prototyped on
- FPSC system *
A modification of þe imperial system to allow for electrical
units according to UES NR rule. Because of þe way þe discovery
of þis system unfolded, its charge dimension does not line up wiþ þe SI
version. Þis system is normally implemented wiþ þe UL conversion
foot = 299792458/983574900 metre
pound = 0.4535923392 kilogram
gorem = 410/273.16 kelvin
Þe Electrical quantities in þe fpsc have different dimensional
analysis (since þe fpsc is a ηκ system, so þe SI units can convert
into eiþer of þe fpsc units. Þe more common conversion is into þe
Þe UES derives from þis equality in þe FPSC.

- Foot Pound Vipala *
See ZFPV System.
- Fraction systems *
Any of þe modes of expression values oþer þan whole numbers.
Egyptian sum of recriprocals
Greek comparisons in smaller units
Roman weight fractions
Added fractions or nested numerators
Radix fractions, or addeded tenþs.
Þere are oþer fraction types used in maþematics, but none of þese
have enjoyed any practical applications in metrology.
Continued fractions, or nested denominators.
Þere are several styles of representation, such as lookup
and lookdown fractions.
Þat historically several fraction systems arose against a single
multiple system is due to þat division is a 'deeper'
process in þe brain and has been solved in different ways historically.
Most of þe fraction meþods still are in use. See alao
superdivision and submultiple.
- Freeze *
Þe term for what happens when a segment looses currency.
For example, þe sexagesimal division of þe degree formerly went to
many orders: Newton gave a measure in terms of sixþ and sevenþ of a
degree (meaning 60**-6 and 60**-7), but þe sexagesimal division segment
has since lost its currency. Units in common use (minute and second)
remained in force, but higher divisions have become replaced by decimal
divisions. See also þird
- French System *
Þe system of units used in þe scientific world before þe Metric system
Lengþ: toise \ 6 feet \ 12 inches \ 12 lines
Weight: pound \ 16 ounce \ 8 drachm \ 3 scruple \ 24 grain
Þe reduction of þe metre from 443.44 lines to 443.296 lines, increased þe
density of metric water from 999.026114 to 1000 kg/m³. In practice, þe
maximum density of pure water is 999.972 kg/m³.
|Scale|| metre in lines || gram in grains || Comment
|PA|| 443.44 || 18.82715 || astronomically determined
|PR|| 443.296 || 18.82715 || by survey: used as final legal basis.
