About the Currency Converter
This currency converter is the quick way to check what a foreign price, a travel budget or an international transfer is worth in your own money. Enter an amount, pick two currencies and the result appears instantly, together with the rate in both directions.
Rates come from a public exchange-rate feed (ExchangeRate-API) that updates once a day. The last rates you loaded are kept in your browser, so the converter still works when you are offline.
How to use
- Enter the amount you want to convert.
- Choose the currency to convert from and to. Use the โ button to swap them.
- Read the converted amount and the exchange rate in both directions below it.
- Tap any row in the Major currencies table to load that currency into the converter.
Mid-market rate vs. the rate you actually get
The converter shows the mid-market rate: the midpoint between buying and selling prices on the global currency market. Banks, card issuers and exchange bureaus add a margin on top of it, so the rate you get is always a little worse.
| Where you exchange | Typical markup |
|---|---|
| Card with no foreign transaction fee | About 0โ1% |
| Regular credit or debit card | About 3% foreign transaction fee |
| Bank wire transfer | About 1โ3% plus a flat fee |
| Airport exchange counter | Often 5โ15% |
When a card terminal abroad asks whether to pay in dollars or in the local currency, choose the local currency. Paying in your home currency (dynamic currency conversion) usually means a worse rate.
Why some currencies are shown per 100 or 1,000 units
One Japanese yen, Vietnamese dong or Indonesian rupiah is worth only a tiny fraction of a dollar, so the table quotes those currencies per 100, 1,000 or more units to keep the numbers readable. The converter itself always uses the exact rate.
FAQ
How often are the exchange rates updated?
The source updates once a day and this page checks for new rates every hour. The time of the rates is shown below the converter. For trading you need real-time quotes from a broker or bank.
Why is my bankโs rate different?
Banks and card networks add a margin or fee to the mid-market rate, and they set their rates at different times of day. Use this converter as a reference for the fair market value.
Does it work offline?
Yes, as long as you have loaded rates on this device before. The converter then uses the saved rates and shows when they were published.
Is the amount I enter sent anywhere?
No. Only the rate table is downloaded; every calculation happens in your browser.
