- zero *
A representation for an empty measure, or place.
It is a mistake to assume that the absence of a particular form of zero
meant the absence of a zero, as some notations do not need to have zero in
all forms. For example, $1.05 can be made of a $1 coin and a 5c coin, with
no requirement for anything to represent the empty 10c column.
- ZFPV *
A system based on a foot of 0.3 m, a pound of 0.45 kgs, and a vipala of 0.4 s.
Used with sexigesimal numbers, it provides an interesting and quite natural system.
The unit of Time is based on the Indian division of the day, and metric approximations
to the Imperial System.
TIME day \ 60 ghurry \ 60 pala \ 60 VIPALA of 0.4 s.
LENGTh mile (1.080 kms) \ 60 chains (18 m) \ foot = 0.3 m \ 60 (5 mm) \ 60 (83.33 mm)
AREA sq mile (1166.4 dka) \ 60 (19.44 dka) \ 60 (324 m2) \ 60 (5.4 m2)
VOLUME cu ch (5832 cu m) \ 60 \ 60 Stere (1.62 m) \ 60 cu ft
CAPACITY tun (1620 L) \ 60 Eimer (27 L) \ 60 Pints (0.45 L) \ 60 (7.5 mLs)
WEIGHT tonne (1.62 t) \ 60 bushels (27 kg) \ 27 Pounds (450 g) \ 60 drams (7.5 g)
SPEED 1 notch = 1 mile per gurry = 1 foot per vipala = 1 pace \ second = 75 cms/sec.
By adding a unit of charge at 1C / 24, electrical units form with the magnetic constant
- zuber *
A tub with two handles, and so a measure of this size.
G. der Zuber means zu (two) + ber (carry, bear), a pot with two carrying things
see amphora, eimer.
