I understand that silver/gold is weighed in troy ounces and everything else in just ounces.
and also that:
12 troy ounces = 1 troy pound
1 troy ounce = 31.1 grams
16 Avoirdupois ounces = 1 Avoirdupois pound
1 Avoirdupois ounce = 28.34 grams
Now here is my question do the grams in both conversions weigh the same? 1 for 1 (not 31.1 = 28.34)
Also what is a good scale that will weigh in all 3 or reg oz & grams?
I also want it to be big enough to weigh cent boxes. All I have now is a postage scale but it only does reg oz in increments of .1 oz |

horgad is right. You actually need at least 2 scales. The larger the capacity of the scale, the less accurate it is for small weights. My postal scale which is one of the use I use for box weights goes up to 72 pounds and does it in pounds and ounces or grams. It is accurate down to 5 grams, which is fine for box weights. For rolls or individual coins I use an Ohaus Emerald scale, which is extremely accurate. I also have a few other scales, including one of those scales the vending industry uses, which are horribly expensive.  |

If that one is off by up to 2 grams at todays silver price it could be off (one way or the other) by over $1.
Is this normal for most gram scales?
He was talking about his 55lb scale. A modern electronic scale with a small capacity will be much, much more accurate. You can't really get one scale that will fit all jobs. I get by with two...a 55lb scale and 100 gram scale. The 100 gram scale is accurate to .1 grams or about 6 cents worth of silver. |

I got a nice 55 lb postal scale on Ebay that measures grams, oz, or lbs with 2 grams or 1/10 oz accuracy. It's $30 with free shipping. If you search for "gram scale" you will find several 1/10 or 1/100 gram scales for $20 to $25, and pocket scales as low as $12. But to get troy oz and regular oz in the same scale is downright rare. |

You can always count on the metric system to be straight forward and consistent. It was designed in part to help get rid of all that confusion. So yes, unlike ounces, grams is grams. As for scales, I do most of weighing in grams and then convert with a calculator when needed. |
