I understand what you mean! I'm scared to death to order any
gold because I haven't a clue as to what a DWT is!
This stuff is really QUITE simple.
"dwt" is an abbreviation for "pennyweight". It is spelled
"dwt" instead of "pwt" because it comes from medieval times,
when jewellers couln't spel goodly. And besides, "pwt" is a
bit too easy to get confused with "PeWTer", which, as anybody
knows, is a rather common (i.e., cheap) metal. Who wants to
buy a very expensive metal like gold if it's measured in
Now then, there are 20 dwt (pennyweight ... or is it
pennyweights ... or maybe pennies-weight?) in an ounce. Well,
no, ... not really. See, there are 20 dwt in a "TROY" ounce.
A TROY ounce is different than a "regular" ounce, in that
there are only 10 of them in a pound. ... er ... that is,
there are 10 "Troy ounces" (often abbreviated "Trounces" in
Renaissance England, thus giving rise to the verb "to
trounce", meaning to pelt with heavy metal. Of course, lead
was and is more popular for this task, but I digress.)
As I was saying, there are 10 Troy Ounces in a Troy Pound. Of
course a Troy Pound is equal to only about 13.56 good ol'
regular ounces, (give or take). Some unscrupulous metals
dealers dreamed this up during the Holy Roman Empire, as a way
to avoid paying their full taxes.
When the Emperor's tax collectors caught on to the scam, the
jewelers were summoned before the Emperor Constantine.
Knowing that "Connie" (as his friends called him) had been
brutalized as a wee lad by being forced to read the Illyiad in
its original Greek, the jewelers told him that they had been
defrauded by some metals merchants from Troy.
With a tear in his eye, the mighty Emperor of the Known
World pardened the jewelers, and promptly declared war
on Persia in retaliation. Emperor Connie knew perfectly well
that Persia had nothing to do with the whole thing, but, it
had access to massive quantities of spices, silks, and
while Troy had a lot of rock.
See how simple it is?
