🇧🇩 Bangladesh Standard Gold Weight Conversion
Complete formula guide based on Bangladesh standard so every subunit (Ana, Roti, Point) mathematically aligns exactly with 1 Vori = 11.664 g.
Gold Weight Conversion (Bangladesh Standard)
| Unit | Relationship | Grams (g) | Formula (in terms of Vori) |
|---|---|---|---|
| 1 Vori | 16 Ana = 96 Roti = 960 Point | 11.664 g | — |
| 1 Ana | 6 Roti = 60 Point | 0.729 g | 1 Ana = Vori ÷ 16 |
| 1 Roti | 10 Point | 0.1215 g | 1 Roti = Vori ÷ 96 |
| 1 Point | — | 0.01215 g | 1 Point = Vori ÷ 960 |
| 1 Gram | — | 1.000 g | 1 Gram = Vori ÷ 11.664 |
| 1 Tola | ~Same as Vori (approx.) | 11.6638038 g | — |
| 1 Kilogram | 1000 g | 85.74 Vori | 1 kg = 1000 ÷ 11.664 Vori |
| 1 Milligram | 0.001 g | — | 1 mg = Vori ÷ 11,664,000 |
💰 Price Conversion Formulas
Let's define:
V = Gold price per vori (BDT)
G = 11.664 g
| Unit | Formula | Example (if 22K = 216,332 BDT / vori) |
|---|---|---|
| Per Gram | V / G | 216,332 / 11.664 = 18,547 BDT/g |
| Per Ana | V / 16 | 216,332 / 16 = 13,520.75 BDT/ana |
| Per Roti | V / 96 | 216,332 / 96 = 2,253.46 BDT/roti |
| Per Point | V / 960 | 216,332 / 960 = 225.35 BDT/point |
| Per Kg | (V / G) × 1000 | 18,547 × 1000 = 18,547,000 BDT/kg |
| Per Milligram | (V / G) / 1000 | 18.547 BDT/mg |
| Per Ounce | (V / G) × 31.1034768 | ≈ 577,103 BDT/oz |
| Per Pound | (V / G) × 453.59237 | ≈ 8,416,500 BDT/lb |
