- Target Currency: The currency you're converting to (e.g., EUR).

Using Our Currency Converter
Try This Example
Convert 100 USD to EUR using our tool, then answer:
If 1 USD = 0.92 EUR, how many euros will you get? What if the rate changes to 0.85?
2. Practice Problems
Problem 1: Travel Budget
You're visiting Japan with 500 USD. Using today's USD/JPY rate:
- How many yen will you receive?
- If a meal costs 2000 JPY, how many USD is that?
Example: At 1 USD = 150 JPY → 500 USD = 75,000 JPY. 2000 JPY ≈ 13.33 USD.
Problem 2: Arbitrage
If 1 EUR = 1.10 USD and 1 USD = 110 JPY, what's the EUR/JPY rate? (Hint: Multiply the rates)
1.10 USD × 110 JPY/USD = 121 JPY/EUR.
⚠️ Common Student Errors
- Dividing instead of multiplying when converting (e.g., using 1/rate).
- Ignoring fees (banks often charge 3-5% extra).
- Using outdated rates (always check the date).
