Non-Frequently Asked Questions About Hectograms to Pennyweights

Questions nobody should ask - but someone did.

  • You would have about 64 pennies, or 64 cents. That is enough for exactly nothing at a jewelry store. The irony of a unit called 'pennyweight' producing less than a dollar when counted as pennies is the kind of linguistic joke that only measurement historians find amusing.

  • Originally, yes. In medieval England, the silver penny coin weighed exactly one pennyweight - roughly 1.555 grams. Over the centuries, pennies were debased and their metal content reduced, but the weight unit stayed fixed. Today's copper-plated zinc penny weighs about 2.5 grams, heavier than the pennyweight it was named after.

  • Not even close. One pennyweight of gold at current prices costs about 40 to 50 dollars. So 64 pennyweights of gold (one hectogram) would cost roughly 2,500 to 3,200 dollars, while 64 pennies is just 64 cents. The ratio of gold's value to its pennyweight count has grown by a factor of roughly 5,000 since medieval times.
