Understanding Gold Rate Conversion

Gold is traded globally using various measurement units and purity levels. Whether you are an investor, a jeweler, or someone looking to sell old scrap gold, understanding how to convert weights and determine the value of different karats is essential. Our Gold Rate Conversion Calculator simplifies this complex math, allowing you to switch between Grams, Troy Ounces, and Tolas instantly.

Gold Purity and the Karat System

The "Karat" (K) is a measurement of the ratio of gold to other metals or impurities. 24K is considered "pure gold." As the karat number decreases, the percentage of gold decreases:

  • 24 Karat: 99.9% Pure Gold (Too soft for most jewelry).
  • 22 Karat: 91.6% Pure Gold (Common in bullion and high-end jewelry).
  • 18 Karat: 75.0% Pure Gold (Standard for luxury watches and rings).
  • 14 Karat: 58.3% Pure Gold (Popular for durability in daily wear).

Common Gold Weight Units

Depending on your region, gold may be measured differently:

  1. Gram (g): The standard metric unit used globally.
  2. Troy Ounce (oz t): The standard unit for international gold spot prices (1 troy ounce ≈ 31.1035 grams). Note: This is different from a standard kitchen ounce.
  3. Tola: A traditional unit used primarily in South Asia (India, Pakistan, Bangladesh), equivalent to approximately 11.66 grams.

Real-World Calculation Example

Suppose you have a 10-gram gold chain that is 18K purity. If the current market price for 18K gold is $45 per gram, your calculation would be:

Total Value: 10g × $45 = $450.00
Pure Gold Content: 10g × (18/24) = 7.5g of pure 24K gold.

How to Use This Calculator

1. Enter the Weight of your gold item.
2. Select the Unit (Grams, Ounces, etc.) that matches your weight input.
3. Choose the Karat of your gold item.
4. Enter the Current Market Price per the unit you selected. (For example, if you selected "Grams," enter the price per gram).
5. Click Calculate to see the total value and the equivalent weight in pure 24K gold.
