Quick answer
Gold purity is shown as karat or fineness: 24K is 999 (99.9% pure), 22K is 916, 18K is 750 and 14K is 585, and the BIS hallmark prints it as 22K916. So 22K gold costs about 91.7% of the 24K rate: if 24K is ₹1,00,000 per 10 g, 22K is about ₹9,169 a gram. A 10 g 22K chain holds 9.16 g of pure gold.
How to use this calculator
- Enter today's 24K rate per 10 g from your jeweller or IBJA.

Frequently asked questions
What does 916 gold mean?
916 means 91.6% pure gold, which is 22 karat. It is the most common purity for Indian jewellery.
Why is 24K not used for jewellery?
24K gold is too soft for most designs, so jewellery is made in 22K, 18K or 14K, mixed with copper, silver or zinc.
How do I check purity?
Look for the BIS hallmark: the BIS logo, the purity (like 22K916) and a 6-character HUID, which you can verify in the BIS Care app.
