Pearl weight

from Wikipedia, the free encyclopedia

The pearl weight determines the size of cultured and natural pearls and represents the differences for the trade. Today, different weight systems such as carat , Kan , Chego and Mangalin are known. The word “pearl weight” is also used as a synonym for a small mass.

Abas

The abas was a pearl weight in Persia . It was:

  • 1 Abas = 3 4/5 As = ⅞ carat (Prussian)
  • 1 Abas = 0.1458 grams = 3 1/30 Aß (Dutch)

Calanchi

The old pearl weight Galanchi was used in the French administered city of Pondichery in East India . It was:

Chego

Chego was a weight for pearls on the Indian island of Goa administered by Portugal and was comparable to the carat. It was:

  • 5 (4) Chego = 1 carat
  • 12 carats = 100 Chego

The measure did not follow any rule when equating to the carat and was not linear, because 24 carats corresponded to 400 chegos. There was a value for each number of carats. Selection of some values ​​for comparison:

  • 5 carats = 21 Chego
  • 10 carats = 69 Chego
  • 18 carats = 225 Chego
  • 24 carats = 400 Chego
  • 36 carats = 900 Chego

  • 1 tang = 330 chouw
  • 1 Tang = 24 Ruttees = 96 Quarters = 384 Anna = 4.6655 grams
  • 1 tang = 24 rutters = 480 vassas = 30.32575 grams

Mangelin

Mangelin was also calculated as the old pearl weight. The weight in Madras , a former province of British India, was 0.3888 grams . Other sources put the value at 0.349 grams.
