Quote: Weights should either be given in grains, or exact troy oz or avoirdupois oz, not "half or quarter" pounds, without specifics. - BiggFredd I agree. Pounds and fractions thereof are confusing. Even grams would be an improvement.

Thank You Ed and Fredd I agree....
Like we were talking about gold coins being LESS popular in foreign form via the tougher calculations to get a true gold weight....
Why don't dealers just list for an odd ball example the total weight of coin what ever that is, and the gold content being say 3.18 grams of gold?
I think the common noob like myself can relate to a Mexico 5 gold peso being 4.2 grams of gold, instead of listing it as (.1205) troy, which is just confusing to most and steers them away....
Biggfredd, could you show me a simple formula to translate that (.1205) figure for example into say 4.2 grams so I can figure out other coins in the futures gold weight, as I am no math wiz like yourself?

I understand the problem these rounds create, being from random Mints, however I don't think there should be any confusion in this case, because the OP clearly said it was 1/2 TROY pound.

I always just remembered a 50 peso was 1.2056 tr oz, and calculated accordianly. The world standard for gold is tr oz and pennyweight (dwt), which are 1/20 of a tr oz. Calculating in grams simply confuses people. Quote: Biggfredd, could you show me a simple formula to translate that (.1205) figure for example into say 4.2 grams so I can figure out other coins in the futures gold weight, Again, if you multiply spot (or rover, or whatever puppy you have handy) by that decimal, you get gold value. There's 31.103 grams to the tr oz, so you'd simply multiply 31.103 by the decimal portion of an ounce (in this case .1205), to get 3.75 grams. Your next question is prolly "why 3.75 g instead of 4.2 g?" The coin weight is 4.2 g, but that includes an alloy. Only 90% is gold, so 4.2*0.9 = 3.78 (rounding error accounts for the rest, it prolly was 4.166666*0.9 = 3.75). If it was 22K, like AGE, you'd multiply the coin weight by 22 and divide by 24. Once you have your gram gold weight, you have to multiply that by the value of a gram of pure gold, which is the tr oz figure divided by 31.103. If your eyes have glazed over by now, quit making it difficult for yourself. Multiply spot by that .1205 figure, and that's the value of the gold. There are times to use the metric system. This ain't one of them.

Nice, thank you BF!!
Now that makes exact sense and that would have been my next question, lol. Esp the part about 4.2 really being 3.75 via to account for the other 10% alloy....
And a fellow who was selling the Mexico 5 peso had it listed as total weight, 4.2 grams, so he was not false advertising for example, as he was not claiming 4.2 grams of gold, as he had gold amount listed as (.1205)....
In the end, I think if the dealers took a minute to apply those formulas and list total coin weight, then total gold weight in grams, they would sell more in the long run....

We try to remember to list pure weight in troy and grams, gross wt, purity, karat, and anything else that might help the sale.
Same way on other items, include weight and dimensions in American and metric.

Quote: Calculating in grams simply confuses people. Those of us who have used the metric system for a long time are not confused by grams. I agree that some people are confused by them, though. We had a great opportunity to go metric back in the 1970s but blew it. Remember all those metric road signs we had that also included English measurements on them? The English measuring system sucks so bad that even the English no longer use it. They do have a few left-overs, though. I was intrigued to see all of their speed and distance road signs in metric measurements but would also see signs that read "Turn-off ahead, 440 yards". They could just as easily have said "400 meters" and been reasonably close but they didn't. I guess that miles and fractions thereof are still with them for now.

I have a 2000 1/2 pound Silver Eagle as well....when weight, it comes out to 6 troy ounces....so it's a little deceiving. Be careful.

Ed-
Even Latin is metric. I remember where "millia passum" was always translated as "a mile". Since it means "1000 paces", it would be almost exactly a km, nowhere near a mile.
The biggest stumbling block to adapting the metric system is that so-called "educators" insist on trying to teach it as conversions from English measurements. That's stupid. If you want the metric measurements of a desk, you don't measure it in feet and inches and convert to meters. You pick up a meter stick and measure it.
LL-
Not at all deceiving. A half pound of silver is exactly 6 troy oz.

The trick would have been to convert all of the old English measurements to metric for commercial applications, which was done to some extent with 3.785L bottles of milk. Had they done that with ALL food and beverage packages, it would not have been long before people tired of all those oddball sizes and requested that they be rounded. That would give us 4L milk bottles, 250 ml pop containers, liters of mayonnaise, etc. Of course, it is doubtful that we ever would have seen 10 eggs in a carton.  As to the metric system... technically, it was standardized by the French, in the late 1700s, if memory serves me. Some of the people I used to work with were real characters and, as great aficionados of the metric system, took great delight in coming up with new English system measurement absurdities... such as furlongs per fortnight as a velocity measurement.

I wrote a webmaster about some obvious errors on his page of conversions, stuff like hogsheads and jeroboams and equally obtusescure measurements. In several years of existence, I'm sure everyone else just looked at the numbers and said, "yeah, whatever".
Then again, in high school, we used to like finding errors in the calculus problems they provided answers to.

In fact, we treated things like that as Easter eggs to be found and held up as trophies. Our physics teacher even offered extra credit points for such finds.

Sorry to dig up such an old topic, but I just want to finish this topic off for good. These 1/2 lb silver rounds are indeed, 6oz. They are not 8 ounces like I've heard other people say.
They are composed of 2880 grains of silver. There are 15.4323584 grains in a gram
so......
2880/15.4323584 = 186.6208 grams 186.6208/31.1 = 6 troy ounces

Use this calculator: http://www.convert-me.com/en/convert/weightThis will show you the weight in various systems. It will even convert your Troy Ounces to Taels (common gold measurement in the Orient) but not into Tolas (common gold measurement in India and South Asia). http://vietnambusiness.asia/sjc-sel...-three-days/

 big bobber Your calculations, while unnecessarily complex (2880 grains/480 grains troz = 6 ounces) are only true for some of these. One company admits they made theirs 8 troz rather than have customers think they were shorted.
