Why Does India Use So Many Weight Units?
India's jewellery trade spans centuries and dozens of regional cultures, each with its own measurement tradition. The tola was standardised under Mughal administration as the base unit for silver and gold taxation — one tola weighed exactly as much as a silver rupee coin (11.664 grams). It remains the dominant unit across North India, Gujarat, and Rajasthan.
The sovereign originated from the British gold sovereign coin, which contained 7.32g of pure gold but was commonly traded in South India as an 8-gram unit. Tamil Nadu and Kerala jewellers still quote prices per sovereign, and bridal sets are typically counted in sovereigns.
The ratti comes from the Sanskrit word for the gunja seed (Abrus precatorius), whose dried seeds were remarkably uniform in weight (~0.1215g) and were used as counterweights on balance scales by Indian gemstone traders for over 2,000 years. Internationally, carats have replaced rattis, but local stone dealers still use rattis for rubies, sapphires, and emeralds.
The government of India now mandates grams for commercial transactions, but traditional units persist in everyday jeweller conversations because buyers and family elders are accustomed to them.
Frequently Asked Questions
1 tola equals exactly 11.664 grams. This is the traditional Indian gold measuring unit still used extensively in North India, Gujarat, Rajasthan, and across Pakistan. When jewellers say "5 tola gold chain", they mean a chain weighing 5 × 11.664 = 58.32 grams.
A sovereign equals 8 grams of gold. It is the standard unit for gold in South India, especially Tamil Nadu and Kerala. Bridal jewellery sets in these regions are priced and weighed in sovereigns. For example, "20 sovereign set" means 160 grams of gold jewellery.
1 carat = 0.2 grams (international standard). 1 ratti = 0.1215 grams (Indian traditional). So 1 carat = approx. 1.646 rattis. When Indian gemstone dealers mention "5 ratti ruby," it weighs about 0.6075 grams or around 3 carats. Both measure gemstone weight, not gold purity.
1 troy ounce = 31.1035 grams. This is the global standard for gold, silver, and platinum trading. International gold prices quoted on COMEX or MCX are in troy ounces. To get the per-gram rate, divide the ounce price by 31.1035.
Masha (0.972 grams) is largely obsolete but occasionally used by traditional craftsmen and older jewellers, particularly for small items like nose pins and ear studs. 12 mashas = 1 tola. It was part of the traditional Indian weight system along with ratti (smallest), masha, and tola.
