How many grams does 1 U.S. penny weigh?
Assuming you are referring to United States Lincoln cents:

1909-1981 (except 1943) (95% Copper and 5% Zinc) - 3.11 grams (147 to the pound)

1943 pennies are steel with a zinc coating and weigh about 2.7 grams (about 168 to the pound).

1983- to date (2.5% Copper and 97.5% Zinc) - 2.500 grams (181 to the pound)

In 1982, both the 95% copper and 97.5% zinc varieties were made - there is no easy way (other than by weighing them) to differentiate between them.

Ounces

To convert grams to ounces, divide by 28.35
