Satapatha brahmana mentions shatamana system which is equal to 100 Krishnala or 100 ratti

[W.11]

1 masha coin (or 1/4 karshapana) = 8 ratti (smallest unit in IVC)

1/2 karshapana coin = 16 ratti

1 karshapana coin = 32 ratti

the same is true for the indus weights

smallest weight = 8 ratti

the multiples of this unit is 1:2:4:8:16:32

You're implying the that the "ratti" and its variations emerged from the ivc and was adopted elsewhere in the subcontinent as a unit of measurement?

 

[W.11]

either it was adopted through out india or it was already present cannot be known, but it is atleast known that ratti, its binary weights etc were present long after IVC collapsed.
