Gold Price per Ratti: What Is a Ratti & How to Convert to Grams

Gold Price per Ratti: What Is a Ratti & How to Convert to Grams

In parts of North and Central India, gold jewellery is still quoted and weighed in rattis - a traditional unit inherited from the pre-metric system. If your jeweller quotes you a ring 'of 8 rattis' or a nose pin 'of 1.5 rattis', you need to know how to convert this to grams to verify the price.

This guide explains what a ratti is, the conversion factor, and how to calculate today's gold price in rattis.

At a Glance

What Is a Ratti?

A ratti is a traditional Indian unit of weight originally based on the weight of a ratti (gunja) seed - the red and black seed of the Abrus precatorius plant. It was used across India for weighing gold, gemstones and medicines before metric standardisation.

1 ratti = 0.1215 grams (the commonly used conversion in modern practice)

Note: regional variations exist - some markets use 0.121g, others 0.1215g. For practical purposes, 0.1215g is the standard.

Ratti to Gram Conversion Table

How to Calculate Gold Value in Rattis

Step 1: Convert rattis to grams: Grams = Rattis × 0.1215
Step 2: Confirm the karat (22K, 18K etc.) from the hallmark
Step 3: Apply IBJA formula: Grams × Purity fraction × ₹15,250/g

Example: 8-ratti 22K nose pin:
8 × 0.1215 = 0.972g
0.972 × 0.916 × ₹15,250 = ₹13,578
