About Currency Converter

Exchange rates float constantly, driven by interest rate decisions, trade flows, and market sentiment, so a currency pair can move meaningfully within a single day. This converter fetches current rates rather than relying on a static table, which is the only way a currency conversion stays useful for more than a few hours.

People reach for this kind of tool when planning travel budgets, comparing prices on international shopping sites, invoicing clients in a different currency, or getting a rough estimate before sending money abroad. It's built for quick, everyday comparisons rather than for executing a transaction.

The rate displayed is the mid-market rate — the midpoint between what currency traders are buying and selling at — not the rate a bank, card network, or money-transfer service will actually give you. Those providers add their own margin and fees on top, so the amount you receive when converting real money is typically a percent or two less favorable than the figure shown here.
