Chan.
The unit in the dealer's system is called a Chan ^ (plural, AcWat
) ; and it should be clearly understood that this Chau, thougli
derived from a weighty is not itself a weight. Chaus are of 4 kinds^
obtained by an identical process from the 4 different Mithqals whicli
follow:—
Bahrain Mithqal *
Qatar do. ^
Bombay do.
Poona do.
= 160 grams Troy.
= 160 do. do.
=74 do. do.
=68? do. do.
Kates.
In each case the number of Chaus in a pearl is found by squaring the
weight (in Mithqals) of the pearl and multiplying the result by 330.
Thus let c be the number of Chaus and m the number of Mithqals, then
c = m* x 330
and the result (c) will be in Bahrain^ Qatar^ Bombay or Poona Chans
according as the weight of the pearl was expressed in Bahrain, Qatar^
Bombay or Poona Mithqals. One Bahrain Chau, it should be observed
is approximately equal to 4 Bombay Chaus ; for, let m be the weight of
the pearl in Bahrain Mithqals, then its weight in Bombay Mithqals is
Vi 0 m ) all( i ^ follows that the number of Bahrain Chaus in the pearl in
question is to the number of Bombay Chaus in the same as 330m 2 is
to 330 x ( V t m )* as 1 to ^y 1 ^. In the same manner it may
be demonstrated that 1 Qatar Chau represents approximately the same
quantity of pearl substance as 4f Bombay Chaus.
Both Arab and Indian dealers have rules of thumb for the convenient
calculation of Chaus from weights, but both classes have recourse by
preference to ready reckoners in Arabic and Gujarati which are obtainable
from Bombay. The (simplified) Arab rule is : Express the weight of the
pearl in Habbahs (of which there are 66 to the Bahrain or Qatar
Mithqal), square the number of Habbahs, increase the result by 1 per
cent., and divide by 100. The (simplified) Indian rule is: Express the
weight of the pearl in Rattis t (of which there are 24 to the Bombay or
Poona Mithqal), square the number of Eattis, multiply by 55 and divide
by 96. Algebraic analysis will show at once that both of these rules are
virtually the fundamental rule
c z=zm i x 330
thrown into a different form.
The Chau, to whichever category belonging, is divisible in the
instance into 100 Dukrahs (plural, Duwakir yjy ). In the case
of the Arab Chau each Dukrah is again resolvable into 100 Mazur jtfi
while in the case of the Indian Chau the Dukrah consists of 16 Badams
first
and the Badam of 16 Visvasis ^
When the number of Chaus in a pearl has been ascertained it only
remains, in order to determine its value, to apply the market rate per
• These are both exceptional weights and ave called Snrati
The
ordinary Bahrain and Qatar Mithqals (the former called also Mashhad ASithqfil) are
much heavier, being equal respectively to 6 and 7 Bombay Mithqals, but they are
tsed in Chau calculations. ^
t The Ratti again is composed of 4 Dans, the Dfin of 4 Anahs and the Anahof ^
Uukrahs.
