Ounce= oz
Pennyweight= dwt
Gram= g
Grain= gr
One pound troy is 12 ounces troy (and that is a lot of gold).
One ounce is 20 pennyweight
There are 31.1 grams in one ounce troy.
So, there are 1.555 grams in a pennyweight.
One pennyweight is 24 grains. So, there are 15.43 grains per gram.
Or, one grain is 0.00017 pounds troy. That doesn't sound like very much. But, one grain is better than none.
By the way, if one ounce of gold (pure gold) is $270, then:
One Gram would be worth about $8.68.
One Pennyweight would be $13.50.
And one grain would be $0.56.
So, if someone offered you gold for, say, $16.00 a gram, it works out to $497.60 an ounce.

16 ounces = 1 lb = 256 drams = 7,000 grains
