Gold Polish Calculator — Ratti/Tola Loss → Tola Output
The fully South-Asian polish calculator: input in ratti-per-tola, output in tola/masha/ratti. Every variable stays in local units, matching the daily-ledger reckoning at Karachi Sarafa Association and Mumbai Zaveri Bazaar shops.
This is the variant used by traditional jewellers who price, weigh, settle and book entirely in tola units, avoiding any gram conversions.
Pure tola/masha/ratti polish reckoning
Polish loss (ratti) = Gross tola × polish ratti/tola. Net ratti = Gross ratti − Polish ratti. Convert back to tola/masha/ratti using the 96/8/1 hierarchy.

Frequently asked questions
Why never use grams in this variant?
When both customer and shop deal in tola/masha/ratti, every gram-conversion step introduces rounding. Keeping the math entirely in local units avoids that.
