d is the abreviation for the old english penny. Which was supposed to weigh 1.56g or one pennyweight. Technical. There is no "supposed". A dwt is a dwt. You can weigh a dwt on a gram scale, just like you can measure a square yard of carpet in meters, but that only changes the weight system, not the weight. Quote:
I agree that there should be some kind of standard measuring system so no matter who you are buying or selling to it's the same measuring system. If we're going to use one system, it would be the metric system, used almost everywhere but the US, which has fought it repeatedly. Quote:
Maybe someone can start a petition for this but what measuring system should be used? No need. Quote:
In the Omnibus Trade and Competitiveness Act of 1988, the United States government designated the metric system of measurement as "the preferred system of weights and measures for U.S. trade and commerce" |

there is a better chance it will be 100 degrees tomorrow in Fargo ND then there will be a common, consistent measuring system used by everyone. I guarantee it will be at least 100°K in Fargo tomorrow. |

There is a standard measuring system, Troy ounces are universal for bullion while pennyweight is typically used for small bits of scrap jewelry that tend to weigh much less than 1oz Dwt and troy oz and grains are all part of the same system, like mills, cents, dimes and dollars. Carats are metric. Hundredweight (cwt) is a hundred av #. Edited by biggfredd

Grams didn't even exist until a couple centuries ago. Yep... I want to say 1805 for the birth of the metric system but don't recall if that is exact. It should be pretty close though. Quote:
If we're going to use one system, it would be the metric system, used almost everywhere but the US, which has fought it repeatedly. Agreed! We had a perfect chance to switch to metric about 30 years ago but the opportunity was muffed. All they really needed to do was continue to package everything in the usual sizes but with grams or mls on the label for weight and volume. Pretty soon, people would have been tired of all the odd-ball sizes, like 287 ml or 28.5 grams, and switching from that to 300 ml and 30 gram sizes would have been a snap. Anyone else remember all the metric US road signs that were posted way back when? That lasted for a few years and then went away, apparently due to lack of interest. When my wife and I visited the UK back in 2001, we noticed that all of their road signs were in metric, except for the signs announcing turns. Practically all of them read "turn ahead - 440 yards". Yards? Holy cow! Why not just say 400 meters? That isn't exact but it is close enough for driving purposes. It's funny how some quirks just resist the changing times. |

Isn't the 20 DWT in an oz? 240/6= 40 Am I missing something? Why are you dividing by 6 instead of 12? |

"Technical. There is no "supposed". A dwt is a dwt. You can weigh a dwt on a gram scale, just like you can measure a square yard of carpet in meters, but that only changes the weight system, not the weight."
Good call there, as I was wondering why not pwt instead of dwt. I can blame the English on that one no doubt, lol...
Also, the part about measuring a square yard in meters or yards makes sense, as like you said it is just simply a DIFFERENT FORMULA system and the weight is the same, or measurement....
"By regular , it simply means the avoirdupois weights that are used for everything but PM. When you talk about weighing PM, forget about everything but troy weights, and leave your regular scales at the door."
That also makes much sense, but I am not a big fan of the word "avoirdupois", as it must be Latin and a real pain of a word to try an log into the storage banks, lol....
So would it be safe to say....
TROY/dwt weight=eons
GRAMS/avoirdupois=a couple of hundred years
Is it me, or does the second listed there make you wanna smack the inventor of that system right in the mouth....

Metric system is beautiful, and actually has a short learning period.
How much does a cubic yard of aluminum weigh in pounds?
To solve the comparable problem in metric all you need is the SpG of aluminum.

Good call Ed, I needed to sound it out better, lol. That pois at the end should have been the dead give away for me....
I will give the French this, they are masters of playing both sides in diplomacy, perhaps the one thing that has kept them a country for so long, jammed right in the middle of a not so solid geographical position. Via, they have ticked off just about every country to every direction of France, lol....
And thanks to ol Ben and his lady skills, they did indeed play a huge role in our country's independence, via that naval blockade at Yorktown....
