Gold Polish Calculator — Ratti-per-Tola Loss → Grams Output
Polish loss rates can also be quoted in ratti-per-tola (a more granular South Asian metric — 8 ratti per masha, 96 ratti per tola). Common rates: 4 ratti, 6 ratti or 8 ratti per tola of polish loss, equivalent to 0.486 g, 0.729 g or 0.972 g per tola.
This calculator accepts the ratti-per-tola rate and returns gross-minus-polish weight in international grams, ready for refining-yard intake or international valuation.
Ratti/tola polish in grams
Polish loss (g) = Gross tola × ratti-per-tola × 0.1215. Net = Gross − Polish. Example: 5 tola gross, 8 ratti/tola → polish = 5 × 8 × 0.1215 = 4.86 g; net = 58.32 − 4.86 = 53.46 g.
