The calculator uses the formula:

Where:

• \( N \) — Number of nickels (dimensionless)
• \( P \) — Number of pennies (dimensionless)

Q3: How would I get whole nickels only?
A: Round down the result to the nearest whole number (using floor() function).

Q4: Can I convert back from nickels to pennies?
A: Yes, multiply nickels by 5 to get pennies.

Q5: Does this work for other coin conversions?
A: Similar principles apply (e.g., quarters to dollars divide by 4, dimes to nickels multiply by 2).
