How Many Grams in an Ounce of Gold? The Honest Hull Guide

If you are weighing up gold, silver, or platinum, there are exactly 31.103 grams in a Troy ounce. This is the only measurement that matters in the precious metals industry. If you use a standard kitchen scale, you might see 28.35 grams in a standard ounce—but using this standard measurement for precious metals is a costly mistake that could leave you seriously out of pocket.

At Big Gold Jewellery & Bullion on Jameson Street in Hull, we believe in straightforward, honest business. We do not hide behind complicated jargon or confusing math. Understanding the difference between these two measurements is the first step to ensuring you get every single penny your gold is worth when you decide to sell.

The Golden Difference: Troy Ounce vs. Standard Ounce

To understand why your gold is weighed differently, we have to look at how the world measures weight. Most everyday items—like flour, sugar, or parcel post—are measured using the Avoirdupois system. In this system, one standard ounce equals roughly 28.35 grams.

However, precious metals have been measured using the Troy weight system since the Middle Ages. A Troy ounce is heavier, weighing exactly 31.1034768 grams (usually rounded to 31.1g for trade). Here is a quick comparison to keep handy:

Measurement Type	Grams	What It Measures
Troy Ounce (ozt)	31.10g	Gold, Silver, Platinum, Bullion Coins
Standard Ounce (oz)	28.35g	Groceries, Post, Everyday Weights

Why does this matter to you? If an unscrupulous buyer weighs your gold on a standard scale and pays you based on a 28.35-gram ounce, you are losing nearly 3 grams of gold per ounce. At today’s high gold values, that missing weight represents a significant amount of money left on the counter.

Reciprocity: How to Protect Yourself from Hidden Fees

We want you to be fully informed before you step foot into any jewellery shop or bullion dealer. Here are three practical tips to protect yourself from common gold-selling traps:

• Check the Scales: Always ensure the dealer’s scales are trade-approved and clearly visible to you. The weight should be displayed in grams or Troy ounces, not standard ounces.
• Know Your Carat: The weight in grams is only half the story. The purity of your gold (9ct, 14ct, 18ct, 22ct, or 24ct) determines its actual value. A 31.1g Troy ounce of 9ct gold contains less pure gold than a 31.1g Troy ounce of 18ct gold.
• Beware of “Postal Gold” Kits: Sending your gold away in a prepaid envelope often means you lose control of the transaction. You cannot see the scales, and you may be hit with hidden testing fees or low-ball offers that are difficult to reject once your items have left your hands.

Frequently Asked Questions

Why is gold measured in Troy ounces instead of normal ounces?
The Troy weight system dates back to the Middle Ages and was specifically designed for precious metals to ensure standardisation across international trade. It has remained the global standard to prevent confusion and ensure high-value metals are measured with extreme precision.

How can I convert standard ounces to Troy ounces?
To convert standard ounces (oz) to Troy ounces (ozt), multiply the standard ounce figure by 0.911. For example, a 10 oz kitchen scale reading of silver is roughly equivalent to 9.11 Troy ounces.

Do you buy broken or damaged gold jewellery?
Yes, absolutely. We buy gold in any condition. Whether it is a broken gold chain, a single earring, or a damaged ring, we value it based on its weight in grams and its purity carat, not its aesthetic condition.

What do I need to bring to sell my gold?
To comply with UK legal requirements, please bring along a valid form of photo identification (such as a driving licence or passport) and a recent proof of address (like a utility bill or bank statement dated within the last three months).
