How many pennys in an ounce?

Answer 1

The coins are technically called cents, and all US Coins are standardly measured using metric units. Modern US cents (mid-1982 and later) weigh 2.5 gm, so converting that to ounces gives 2.5/28.35 or 0.0882 ounces.

Older US cents were made of different metals. The most common bronze alloy coins weighed 3.11 gm, or 0.1097 oz.

Answer 2

It depends on the date. Cents before 1982 weigh 3.11 gm. Cents from 1983 onward weigh 2.50 gm. Both kinds were struck during 1982, so if you have a cent with that date you can't tell unless you have a sensitive scale.

Answer 3

Assuming you are talking about the Troy Ounce (used for weighing precious metals), there is 20 Pennyweights per Troy ounce. However there is 18.229 166 667 Pennyweights to the Avoirdupois Ounce (the standard ounce weight).

Answer 4

The pennyweight is equal to 1/20th of a troy ounce. There are 1.09714286 ounces in a troy ounce, so there are 18.2292 pennyweights in one ounce.

Answer 5

penny = 2.5g

oz. = 28.3495231 grams

oz./penny = 11.3

it takes about 12 pennies to make an ounce.

Answer 6

If the pennies are all dated from 1983 to 2014 they each weigh 2.5 grams. 16 of them = 40 grams. This come out to be 1.4110oz.

Answer 7

1 ounce = 18.2291667 pennyweight
