How to Use the Currency Exchange Calculator
This currency exchange calculator converts any amount between two currencies using the exchange rate you provide. Enter the amount you want to convert and the exchange rate (how much of Currency B equals 1 unit of Currency A). The calculator instantly shows both directions: A→B (multiply) and B→A (divide).
For example, if 1 USD = 1.08 EUR and you want to convert $200, the calculator shows 200 × 1.08 = 216 EUR in one direction and 200 ÷ 1.08 ≈ 185.19 USD in the other. This is useful when you want to know both how much you get when spending and how much you started with when receiving a foreign amount.
This calculator uses the rate you enter with no markup or fees. Real-world currency exchanges through banks or exchange booths typically include a spread (the difference between the buy and sell rate) and may charge additional fees. Always check with your bank for the actual transaction rate before exchanging money.
