Yes, debit cards automatically convert currency for international transactions, using rates set by networks like Visa/Mastercard, but your bank adds its own fees and markups, and you might be offered a choice (Dynamic Currency Conversion, or DCC) to pay in your home currency, which is usually a bad deal. To get the best rate, always choose to pay in the local currency, not your home currency, when prompted at a merchant or ATM, and be aware of your bank's foreign transaction fees, often 1-3%.
