What is the difference between a Troy Ounce, and a Standard Ounce?
This is a very common question, and one that most people have trouble answering without some reference.
Surprisingly there are two totally different methods for calculating silver/gold vs the method used to calculate everything else.
The most likely explanation is that Gold, Silver (and Platinum) are such universal and important materials, that a standard measurement system is not an option but a requirement. That unfortunately means that the people from the United States are at a small disadvantage, when it comes to properly measuring these things with the standard machines we might use in day-to-day life.
Exact measurements are as follows:
- 1 troy ounce = 31.1034768 grams or 480 grains
- 1 ounce = 28.3495231 grams or 437.5 grains
Basic elementary school maths will tell you that 1 Troy ounce contains 2.75 grams more of metal than the standard ounce.
Therefore, an example of this could be that an ounce of Gold would weigh 2.7539537 grams more than an ounce of sugar.
So, in a nutshell: “1 Troy ounce contains 2.75 grams more…”
