1. What is 916 Gold?

916 gold, also known as 22-karat gold, is a popular gold alloy containing 91.6% pure gold mixed with other metals for increased durability. It's widely used in jewelry making due to its excellent balance between purity and strength.

2. How to Calculate Gold Purity?

The gold purity calculation formula is:

Where:

• \( Karat \) — Gold karat value (e.g., 916 for 22-karat gold)
• 24 — Represents pure gold (24-karat)

Example: For 916 gold: \( \frac{916}{1000} \times 100\% = 91.6\% \) purity

3. Understanding Gold Karat System

Details: The karat system measures gold purity, where 24-karat is pure gold. Lower karat values indicate alloys with other metals. Common standards include 24K (100%), 22K (91.6%), 18K (75%), and 14K (58.3%).

4. Using the Calculator

Tips: Enter the gold karat value (e.g., 916 for 22-karat gold). The calculator will automatically compute the purity percentage. Valid karat values range from 1 to 24.

5. Frequently Asked Questions (FAQ)

Q1: What does 916 gold mean?
A: 916 gold means 91.6% pure gold, equivalent to 22-karat gold, with the remaining 8.4% being other metals for durability.

Q2: Is 916 gold good for jewelry?
A: Yes, 916 gold is excellent for jewelry as it maintains high gold content while being more durable than pure gold.

Q3: How is 916 gold different from 24K gold?
A: 24K gold is 100% pure but soft, while 916 gold is 91.6% pure with added strength from alloy metals.

Q4: Can I calculate purity for any karat value?
A: Yes, the formula works for any karat value between 1 and 24, giving the corresponding purity percentage.

Q5: Why is gold mixed with other metals?
A: Gold is alloyed with other metals to increase durability, change color, and reduce cost while maintaining desired gold content.
