How many dwt are in an ounce?

Answer 1

For those who don't know, "dwt" is the standard abbrivation for pennyweight.

The pennyweight was the weight of a silver penny in medieval England.

It is no coincidence that there were 240 pennies to the English pound.

240 silver pennies were equivalent to a pound of silver.

So to answer the original question, there are 20 pennyweights (dwt) in one troy ounce.

1 troy ounce converts to 1.09714286 regular US ounces.
