Scrap Gold & Nugget Weight Calculator

Welcome to the most accurate live gold value calculator. Whether you are a prospector weighing raw nuggets or looking to sell old scrap jewelry, this tool uses real-time global spot prices to tell you exactly what your gold is worth.

How to use the calculator

1. Enter the weight: Type the number from your scale.
2. Select your unit: Choose Grams, Troy Ounces (standard for precious metals), or Standard Ounces (kitchen scales).
3. Select the Karat (Purity): 24k is pure gold. Pick your specific karat to adjust the value for impurities.
4. Choose your Currency: See the value in your local money.

Why Use Our Gold Calculator?

Unlike standard calculators, our tool connects directly to live global financial APIs. We automatically do the complex math required to convert standard "kitchen scale" avoirdupois ounces (28.34g) into official Troy ounces (31.10g) to ensure you never accidentally overvalue or undervalue your metal.

Who can use this tool?

• Gold Prospectors & Detectorists: Instantly check the value of your raw nuggets and pickers out in the field.
• Jewelry Sellers: Find out the true "melt value" of your old rings and necklaces before going to a pawn shop.
• Scrap Metal Recyclers: Quickly calculate bulk yields for e-waste and scrap refining.

Common Jewelry Karat Types

Jewelry is rarely 24k pure because pure gold is too soft. It is alloyed with copper or silver for strength:

• 9k - 10k: Highly durable, common in older rings and discount jewelry.
• 14k: The most common standard in the US for everyday wear.
• 18k: Premium fine jewelry, offering a rich yellow color and good durability.
• 22k - 24k: Common in high-end Asian and Middle Eastern jewelry, very rich in color but prone to scratching.
