Gold holds immense cultural significance in India, symbolising wealth, tradition, and a preferred investment avenue. When buying gold in traditional markets, you may come across a unit of measurement called Ratti . While grams and carats are more common globally, Ratti holds a unique place in India , especially when purchasing jewellery or evaluating gemstones.At Aditya Birla Capital Digital, we believe in empowering you with knowledge, so you make informed decisions when purchasing gold or investing. On that note, let’s understand the conversion of ratti to grams and how it influences pricing and loans.
What Is Ratti? Definition and Origin
The ratti is one of the oldest weight units in India. Traders and jewellers once measured gold and gemstones using the seed of the Gunja plant (Abrus precatorius), a small red berry that grows across tropical India. The seed was chosen because of its consistent weight. Before standardised scales became widely available, a handful of Gunja seeds gave a reliable, repeatable measure.
Today, 1 ratti is fixed at 0.12125 grams, or 121.25 milligrams. This is the figure accepted by financial institutions, regulated jewellers, and government-recognised trade bodies across India.
The ratti unit of measurement appears in ancient Indian trade records and was carried forward through generations of goldsmith families. In modern retail, gram-based pricing has taken over for most jewellery. Yet ratti remains in everyday use among local jewellers, particularly in North India, for quoting gemstone weights and pricing smaller ornaments.
So when a jeweller says a piece is 5 ratti gold, that works out to roughly 0.606 grams. This number is important to know when you are shopping for gemstones, comparing prices of jewelry or thinking of pawning gold ornaments.
1 Ratti to Gram: Exact Conversion Formula
The formula to convert to calculate how many grams in one ratti
Grams = Number of Ratti x 0.12125
5 ratti x 0.12125 = 0.60625 grams.
To go the other way, that is, to find how many ratti in one gram, divide by 0.12125:
Ratti = Grams / 0.12125
Result: 1 gram = 8.2474 ratti. For quick estimates, 8.24 ratti per gram is a practical figure. For financial transactions, always use the full value of 8.2474.
These two formulas cover every ratti gram conversion situation: jewellery buying, gemstone pricing, and gold loan applications.
Ratti to Gram Conversion Table
The table below lists gram equivalents for common ratti quantities. All values use the standardised rate of 0.12125 grams per ratti.
| Ratti | Equivalent in Grams |
|---|---|
| 1 | 0.12125 g |
| 2 | 0.2425 g |
| 5 | 0.60625 g |
| 10 | 1.2125 g |
| 20 | 2.425 g |
Note: Values in this table follow the standardised 0.12125 g per ratti rate. Certain gemstone traders use an older rate of 0.18 g per ratti, especially for astrological stones . That figure produces different results. Always confirm which rate your trader is quoting before agreeing on a price.
Ratti vs Carat vs Tola vs Gram: How Indian Gold Units Compare
India's jewellery and gold markets use several weight units alongside the metric gram. Each unit carries a different gram value and a distinct context of use.
| Unit | Gram Equivalent | Common Use | In Use Today |
|---|---|---|---|
| Ratti | 0.12125 g | Gemstones, traditional jewellery | Yes |
| Carat | 0.20 g | Gemstones, international trade | Yes |
| Tola | 11.6638 g | Gold bullion, older jewellery pricing | Yes |
| Gram | 1.0 g | Modern jewellery, banking | Yes |
The most common point of confusion is ratti vs carat. These are two separate units. One carat equals 200 mg, or 0.20 g. One ratti equals 121.25 mg, or 0.12125 g. A gemstone described as 5 carat weighs 1.0 gram. The same stone described as 5 ratti weighs only 0.606 grams. Treating these as the same figure means overpaying by around 65 percent per unit.
A second confusion worth clarifying: carat and karat are not the same thing. Carat (ct) measures the mass of a gemstone. Karat (k or kt) measures the purity of gold. 22K gold contains 91.6 percent pure gold by weight. The two scales are entirely unrelated.
Tola still appears in some wholesale gold market references and older pricing charts. One tola equals 11.6638 grams. Most modern retail transactions and all banking systems now quote gold weight in grams.
Why Ratti Measurements Matter for Gold Loans
Gold loan lenders assess ornament weight in grams to calculate the loan amount. Older or traditionally crafted jewellery is often described in ratti, particularly in North Indian households.
Here is why it matters
- Enables price comparison in Ratti and Gram.
- Ensures accurate measurement in jewellery making.
- Helps in proper gold valuation for loans and resale.
How to Convert Ratti to Grams Accurately
Here is how you need to do your calculation to convert ratti to gram:
- Find the weight of the ratti from the jeweler's label or tag.
- Multiply the ratti weight by 0.12125. For example, 8 ratti x 0.12125 = 0.97 grams.
- Cross-check with the weight in grams on a certified jeweler's scale with 2 decimal accuracy.
Getting the standard right is not that difficult. It has a directly gives you as idea on what you pay for a gemstone and what a lender will offer you against your gold.
Practical Tips When Buying Gold Measured in Ratti
Buying gold in Ratti can be tricky if you’re not careful. Here’s how Aditya Birla Capital Digital recommends you proceed:
Verify the Conversion

Understand Making Charges
Jewellers charge making fees separately. Ask for a detailed cost breakdown upfront.

Leverage simple tools to convert Ratti into gram and estimate pricing before making a decision.
Buy-Back & Resale Value
Check whether the jeweller offers buy-back policies and know the resale terms before purchasing.
