Have you ever wondered what’s so special about the 1-oz of gold measurment? I sure have, and having been thoroughly confused early on as to what the difference was between say an ounce of gold and an ounce of turkey lunch meat I thought this might be a good topic!
The difference as it turns out lies in the fact that there are two different measurement systems. The everyday or common one we use in the U.S. is called the avoirdupois system, while the one used to measuring gold, silver, and gems is called the troy weight system. One troy ounce is slightly more than one avoirdupois ounce. There are basically 12 troy ounces to every pound, while there are 16 avoirdupois ounces to a pound.
You can also look at the grams of each to see the difference in the measurements. In every troy ounce there is 31.103 grams, while in every avordupois ounce there is 28.350 grams (both rounded to the third decimal).
The troy measurement system is thought to have originated in a French town called Troyes way back in the medieval times. It’s kind of amazing that it is still used as the standard all over the the world for measuring gold. With all the wars and conflicts that have occurred since medieval times the measurement is still in place!
So, what should you take away from this information? Well, one troy ounce of gold will be slightly heavier than one avoirdupois ounce of gold! This means don’t weigh your gold on an everyday food scale you may have in your kitchen! In other words, if you have some scrap gold and you weigh it on a food scale and it says one ounce, and you take it to a gold dealer who measures it you will find it is not one ounce on their scale.
This might be easier to realize by looking at grams… One ounce of scrap gold measured on a kitchen food scale will only be about 28 grams. While a gold dealers troy scale measures an ounce as being about 31 grams. This means that while you may have thought you were taking in an ounce gold to the dealer, you really taking in slightly less than an ounce. If you’re like most people, this info might be important since your probably looking to get the most you can from you gold!
