Chart for gold size to ounce conversion.

[coyote3]

I saw a chart at one time that had an approximate amount of pieces of gold that added up to an ounce. It had the number of pieces 1 micron, 10 micron, 20 micron, and so on up to 100 micron. Does any know where this chart is? Thanks.

How to Calculate Gold Price By Karat & Weight
First, divide the karat (24; 18; 14; 10) by 24. Now multiply that number by today's gold price per gram. So, if you have a five-gram 10K gold ring, and the current price of gold is $1,600.00 per ounce - or $51.45 per gram ($1,600.00 divided by 31.1 grams), then your 10K gold ring is worth $21.44 per gram ($51.45 x .4167), or $107.20.
10k = 10/24 = .4167
14k = 14/24 = .5833
18k = 18/24 = .750
22k = 22/24 = .9167
If you have five- grams of 14K, and gold is $1,600.00 today, then $1,600 divided by 31.1 would equal $51.45. That figure, multiplied by .5833 (14K) comes out to $30.01 per gram. $30.01 x five- grams equals $150.05.
Some gold buyers use pennyweight (DWT) instead of grams. There are 20- pennyweights per troy ounce. Let’s say you want to sell your gold. You know it weighs 25 grams. You go to a pawn shop to see what they will pay, but they use pennyweights, not grams. Here's how to calculate the conversion: 25 grams of gold x 0.643 = 16.1 pennyweights.
Pennyweights to Grams............divide by 1.55517

Grams to Pennyweights............Multiply by 0.643

Thinking ... thinking ... thinking ... ouch! Not sure if this helps - - it is per gram by mesh size.

From goldfeverprospecting.com:

Gold Nugget sizing info: We are often asked how many pieces per gram. It is very hard to predict how many pieces there are per gram as the # of nuggets by weight varies quite a bit per batch. But in general you can expect around 1-2 pieces of gold for 4 mesh, 2-4 pieces of 6 mesh per gram, 7-12 pieces of 8 mesh per gram and around 15-20 per gram for 10 mesh. You can expect many more pieces for smaller 12, 14, and 16 mesh size gold and hundreds for fine gold. Every batch is very different and each piece of gold is natural and of course therefore unique. Some may be flat and light or rounded and very dense (heavy). If you need any help with sizing just email us - we are happy to help.

Ya that helps. I dont know where I seen it rummaging through google one day... but it give the average size in micron or mesh and then said the amount of pieces that will be required to reach an ounce. something like 4800 pieces of 200 mesh to get an ounce?? I dont know for sure, thats why I figured somebody else might have seen it..

coyote,
I've been in parts of Wyoming and it is nice country. I hope you only need the chart to determine how many 1/4" and larger nuggets equal a pound..........63bkpkr

 

[midnightmoon]

One more try ...



It's a GPAA Chart.

 

[63bkpkr]

Is that chart talking Troy oz's? If so you will need only 72 pcs for a pound......63bkpkr

 

[midnightmoon]

Uh oh! you're right, 63bkpkr. Somethings wrong here.

Spinning the beads on my abacus ...

Converted the grams to troy oz with the Gold Fever Prospecting data [on the 10 mesh]. 15-20 per gram [x31] becomes 465-620 pieces per troy ounce.

Compared results to the GPAA chart [on their 1/10 mesh size]. Their figure is 98 pieces per ounce.

The figures don't jive at all.

But, I lean towards Gold Fever Prospecting's numbers being more accurate, because they are selling the stuff. If they are wrong, somebody woulda showed up and poked them in the eye by now.

Thanks for pointing out the inconsistency; I wouldn't want to mislead anyone.

.......or just weigh it and use one if the online gold calculators.

A question: Does anyone have recommendations for a particular brand of digital scale and why you like it along with where to purchase the scale?? Thank you in advance........63bkpkr

I bought mine at a head shop for 20 bucks...I figure the drug dealers are pretty demanding about accuracy ;-)
