Check whether the rate is quoted as USD/EUR (dollars per euro) or EUR/USD (euros per dollar). Using the inverse rate can double your error. $100 × 0.92 = €92, not €108.70.
Banks and airport kiosks charge 2–5% above the mid-market rate. A true €1,840 conversion may cost $2,100+ after fees. Always compare total cost, not just the rate.
