* Nickels are a unit of currency, not weight. You can't directly convert nickels to ounces because they are different things.
* The weight of a nickel can vary slightly. This is because the composition of the nickel can change over time.
To clarify:
* If you want to know how much 5 ounces of nickels weigh: This is possible! You'd need to know the average weight of a nickel, and then multiply that by the number of nickels that weigh 5 ounces.
* If you want to know how many nickels equal $5: This is a different question, and it's easy to solve. There are 20 nickels in a dollar, so 5 dollars would be 5 x 20 = 100 nickels.
Let me know if you'd like to explore either of those scenarios!
