**1 Grams in an Ounce of Gold: Unveiling the Precious Metal's Density**

**Introduction**

Gold, a highly coveted precious metal, holds immense value for its aesthetic appeal, monetary worth, and industrial applications. Its density, measured in grams per cubic centimeter (g/cm³), is a crucial property that determines its weight, durability, and resistance to deformation. Understanding the relationship between grams and ounces of gold is essential for investors, jewelers, and anyone dealing with this valuable commodity.

**Grams per Ounce of Gold: A Precise Conversion**

One ounce (oz) of gold is equivalent to 31.1034768 grams (g). This conversion factor is universally accepted and is widely used in the gold industry. To convert grams to ounces, simply divide the number of grams by 31.1034768. Conversely, to convert ounces to grams, multiply the number of ounces by 31.1034768.

**Physical Properties of Gold**

In addition to its density, gold exhibits several other remarkable physical properties:

• Atomic Number: 79
• Atomic Weight: 196.96655 g/mol
• Melting Point: 1,064.43 °C (1,948 °F)
• Boiling Point: 2,856 °C (5,173 °F)
• Electrical Conductivity: 45.2 mS/m (at 298 K)
• Thermal Conductivity: 318 W/(m⋅K) (at 298 K)

**Applications of Gold**

Gold finds a wide range of applications due to its unique properties and its enduring appeal:

• Jewelry: Gold's malleability and lustrous appearance make it ideal for crafting jewelry, such as rings, necklaces, bracelets, and earrings.
