**US Coin Values:**

| Coin | Value | Per Dollar |
|------|-------|------------|
| Penny | 1¢ | 100 |
| Nickel | 5¢ | 20 |
| Dime | 10¢ | 10 |
| Quarter | 25¢ | 4 |
| Half Dollar | 50¢ | 2 |
| Dollar Coin | 100¢ | 1 |

**The Formulas:**

- Cents to Dollars: Dollars = Cents / 100
- Dollars to Cents: Cents = Dollars x 100

**Minimum coins (greedy algorithm):** The calculator figures out the fewest US coins needed to make any cent amount. It starts with the largest denomination (quarters) and works down. For example, 87¢ = 3 quarters + 1 dime + 2 pennies = 6 coins total.

**Coin counting tip:** Sort coins by type first, then count each denomination separately. Roll completed amounts: 50 pennies ($0.50), 40 nickels ($2), 50 dimes ($5), or 40 quarters ($10) per standard coin roll.

## Frequently Asked Questions

**Q: How do I convert cents to dollars?**

A: Divide the number of cents by 100. For example, 350 cents / 100 = $3.50. To go the other way, multiply dollars by 100: $3.50 x 100 = 350 cents.

**Q: How many quarters are in a dollar?**

A: There are 4 quarters in one dollar (4 x 25¢ = 100¢). Other coin counts per dollar: 10 dimes, 20 nickels, or 100 pennies.

**Q: What is the fewest coins to make 99 cents?**

A: The minimum is 9 coins: 3 quarters (75¢) + 2 dimes (20¢) + 4 pennies (4¢) = 99¢. This uses the greedy approach of always choosing the largest coin that fits.

**Q: How many coins fit in a standard coin roll?**

A: Standard US coin roll amounts are: 50 pennies ($0.50), 40 nickels ($2.00), 50 dimes ($5.00), 40 quarters ($10.00), 20 half-dollars ($10.00), and 25 dollar coins ($25.00). Banks and coin-counting machines accept these standard rolls.
