# what does a Canadian penny weigh? Answered

i'm working on a model plane right now, a mig 31, and you have to add in the weights before you have any chance of actually knowing if they are enough or not. the instructions say to put in 7grams, but i don't know how many pennies i would need for that. can someone tell me how much a penny weighs., or better yet, just how many i need? thanks.

It depends on which year it was made:

Years
2000–present 2.35 g
1997–1999 2.25 g
1982–1996 2.5 g
1980–1981 2.8 g
1978–1979 3.24 g
1942–1977 3.24 g
1920–1941 3.24 g

So three of the most recent issue weigh: 3*2.35 = 7.05 g

Or two of the recent, plus one from '97-'99: 2.35+2.35+2.25 = 6.95 g
Ya know, just in case 7.05 g is too heavy. ;-)
