Understanding Foreign Exchange: How Rates Work
About the Currency Converter
A currency converter turns an amount in one currency into another using an exchange rate: how many units of the second currency one unit of the first is worth. Multiply your amount by the rate to get the converted value.
Rates move constantly. The mid-market rate in a converter is the midpoint between buy and sell prices and is a useful benchmark. The rate you actually get from a bank, card issuer or transfer service is usually a little worse because they add a margin or fee. Compare the final amount received, not the headline rate, to judge the real cost.
Some currencies are pegged to another, such as the UAE dirham, fixed at about 3.6725 per US dollar. Others float and can move noticeably in a day. For a trip or payment due later, treat any converted figure as an estimate and allow a small buffer.
If one US dollar is worth 3.6725 dirhams, then 500 dollars is 500 times 3.6725, which equals 1,836.25 dirhams. Converting back, 1,836.25 divided by 3.6725 returns 500.
Tips for best results
- Rates shown are indicative. Check the rate with your bank or provider before you transact.
- Avoid airport kiosks and dynamic currency conversion at card terminals, which tend to be expensive.

Frequently Asked Questions
What data source powers these currency exchange rates?
Exchange rates are sourced from open.er-api.com, pulling official daily reference rates from the European Central Bank (ECB) and wholesale interbank feeds. Rates are refreshed continuously throughout the global trading week.
Why does my bank or credit card charge a different rate?
Commercial banks, credit card providers, and airport kiosks typically add an undisclosed retail margin (the FX spread) of 2% to 5% on top of the mid-market rate. Toolseza displays the real, uninflated mid-market rate.
Does this currency converter work when offline or with weak signal?
Yes. If network requests are blocked or offline, Toolseza falls back to the most recently cached rates or reliable baseline reference rates, displaying a clear status notification so you always know the data freshness.
What happens to exchange rates on weekends?
Wholesale foreign exchange markets close Friday evening (5:00 PM EST) and reopen Sunday evening. Rates remain steady over the weekend based on Friday's market closing levels.
