Tank (unit)

Tank (cf. Hindostan tānkh "water container") was a unit of weight for precious stones , gold , silver (in Surat ) and a pearl weight in the British Presidency of Bombay and Madras . As a pearl weight, it was not used for pricing. Here one took the measure of Chouw/ Chow as a standard and 330 Chouws / Chows were designated with the nominal tank. Small differences in the two presidencies were the different dimensions. The approach for the prices of the pearls was calculated from the square of the number of tanks times 330. The sum was then divided by the number of pearls and resulted in the number of Chouws.

Gemstone gold silver

1 tank = 30.32575 grams
1 tank = 24 Röttihs / Ruttees = 480 Wassas / Vassas

Pearl weight

1 tank = 4.6655 grams
1 tank = 24 Röttihs / Ruttees = 330 Tuckas
1 Ruttee = 13 ¼ Tuckas = 4 Quarter = 16 Auners

The Chouw divided into

1 Chouw / Chow / Tschoh = 4 Quarter = 100 Docras = 1600 Buddams

The dimensional chain was only an invoice weight to determine the price. Buddem, also Buddam, was a pearl weight in the British presidencies of Bombay and Madras and the smaller measure in the dimensional chain.

Comparisons

1 tank (Bombay) = 12 deficiency (Madras)
1 Chouw (Bombay) = 3 1/18 Chouws (Madras)
55 Chouws (Bombay) = 18 Chouws (Madras)

example

Approach to pricing

Example of 55 pearls Bombay
- 55 pearls weigh 6 tanks; 6 times 6 times 330 = 11,880; 11,880 divided by 55 = 216 Chouws
Example of 27 pearls Madras
- 27 pearls weigh 20 imperfections; 20 times 20 times ¾ = 300; 300 divided by 27 = 11.11 Chouws
