Non-Frequently Asked Questions About Troy Ounces to Ounces
Questions nobody should ask - but someone did.
-
Yes, slightly. A one-troy-ounce coin weighs about 1.097 avoirdupois ounces, which exceeds the one-ounce postage threshold by 0.097 ounces (about 2.75 grams). You would need to use two-ounce postage rates for a single troy-ounce coin, paying a few cents extra for the privilege of mailing $2,200 worth of gold.
-
Countless times. Inexperienced buyers who weigh gold on a kitchen scale (which reads avoirdupois ounces) and compare to troy-ounce prices will overestimate how much gold they need by about 10 percent. The reverse error, weighing gold on a troy scale and selling at an avoirdupois price, loses about 10 percent of value.

Both are real, legal, and widely used, but for different purposes. The avoirdupois ounce dominates everyday commerce in the US and UK. The troy ounce dominates precious metals worldwide. Asking which is 'real' is like asking whether the British or American gallon is 'real': both exist, both are defined, and using the wrong one in the wrong context causes expensive confusion.
