Category:Tasua (gold weight)

The Tasua is a historical gold weight of the Akan in Ghana and the Ivory Coast for the weighing of gold dust.

Regional name variants:

• Pereguan osua
• Ta atape
• Ta atatue
• Ta atakpi
• Benna anrui nyo

The name "Tasua" (= 1 Ta + 1 Sua) is misleading, because it would indicate to a weight around of 70,xx g.
The name "Pereguan osua" would be more to the point because "1 Peregua + 1 Sua = 70,4 g + 17,6 g = 88.0 g".
The prefixes "o-" or "e-" mean singular; "a-" or "n-" mean plural.

Theoretical weight:

- 87,76 g (Abel for 400 Taku)

- 87,78 g (Abel for 600 Ba)

- 88,0 (Garrard)

Real weight:

- 87,5 g (Inventory number MHNT.ETH.2010.25.094 in the "Muséum de Toulouse") (Brass figure two crossed crocodiles with a fish in their mouth.)

Value equivalents:

1 Ta atakpi = 400 Taku = 600 Ba (Abel)

88,0 g mean ca. 45 Ackies

240 Taku = 40 Ackies (Abel)

(1 Ounce = 16 Ackies (European trade))
