How this currency converter works

A currency converter answers one simple question: how much is my money worth in another currency? Enter an amount, choose the currency you have and the one you want, and the tool multiplies your amount by the live exchange rate — the price of one currency in terms of the other. This page is a currency converter with live, daily-updated mid-market rates for more than 160 world currencies, from the US dollar and euro down to the Philippine peso and Vietnamese dong.

Everything runs in your browser: rates are fetched from a free public exchange-rate feed, nothing is sent anywhere, and your last amount and currency pair are remembered for next time. Press the ⇄ button to flip a pair instantly, or tap one of the popular-pair buttons for one-tap conversions on the corridors travellers and expats use most.

How exchange rates actually work

An exchange rate is simply a price: 1 US dollar might "cost" 0.88 euros today and 0.87 next week. Rates move constantly because they reflect real supply and demand in the global currency market, driven by interest-rate decisions, inflation figures, trade balances and political events. When demand for a currency rises, its price rises too.

The rate this converter shows is the mid-market rate — the midpoint between what buyers will pay and sellers will accept. It is the rate you will see quoted in financial news and on the European Central Bank's reference-rate tables, and it is the benchmark every retail rate is built on. No one actually buys currency at exactly the mid-market rate; providers add their own margin (see below), so think of the mid-market figure as the honest baseline to compare everything against.

Rate data here comes from public feeds that aggregate central-bank and market data — the same family of sources behind the ExchangeRate-API documentation and the Frankfurter exchange-rate API — refreshed daily and cached for up to an hour so the page stays fast.

Worked example: converting $1,000 US dollars to euros

Say you are booking a holiday in Spain and want to know what $1,000 buys you in euros. The converter does exactly three things:

• Fetches today's rate. Suppose the mid-market rate is 1 USD = 0.8775 EUR.
• Multiplies. $1,000 × 0.8775 = €877.50.
• Shows the reverse. 1 EUR = 1.1396 USD, handy when you are reading euro price tags.

Try it in the tool above — with today's rates, $1,000 converts to roughly €878. Notice how the tool also shows the inverse rate: converting both directions with one number is exactly how professionals quote currency pairs.

Popular currency pairs and what they are used for

Most currency searches are not for the abstract idea of "conversion" — they are for a specific corridor. These are the corridors people actually look up, and what they typically mean:

*Indicative mid-market figures based on rates on 27 September 2026 — live numbers are always in the tool above. The GBP → USD and AUD → USD rows start from £1,000 and A$1,000 respectively.

Remittance corridors like USD → INR and USD → PHP matter enormously: millions of workers send money home every month, and even a one-percent difference in the effective rate changes how much family actually receives. If you send money regularly, our compound interest calculator shows what those saved fees grow into when invested instead.

Why the 30-day trend chart matters

Rates do not just sit still — they drift. The 30-day trend chart above shows where your pair has been heading, which helps with one practical decision: when to move money. If 1 USD bought 0.86 EUR two weeks ago and buys 0.88 today, the dollar has strengthened — converting now captures more euros per dollar than a fortnight ago.

Two honest caveats. First, a trend is not a forecast: past movement does not predict next week's rate, so use the chart to avoid obviously bad timing, not to gamble. Second, for small amounts, rate timing matters far less than the margin your provider adds — a 2% fee on $500 costs $10, while even a lucky 0.5% rate swing only moves it $2.50.

The rate you see vs the rate you get: margins, fees and travel cash

Here is where real money is lost. Banks, airports and hotels all quote you a rate worse than the mid-market rate and keep the difference — the spread — plus sometimes a flat commission. Airport kiosks are the most expensive offenders; your regular bank card abroad is usually far cheaper.

• Compare against the mid-market baseline. Run your amount through this converter first, then compare with the provider's quote. If €877 becomes €855 at the counter, you are paying roughly 2.5% for convenience.
• Specialist transfer services beat banks. For larger sums — deposits on property, tuition, invoices — dedicated FX services typically quote spreads under 1%, versus 2–4% at high-street banks.
• How much cash to carry. A common rule of thumb: enough local currency for the first 24 hours (taxi, food, tips), then use cards or ATMs. Dining out abroad? Convert the bill with the tool above, then check what is customary locally with our tip calculator before you pay.
• Retiring or relocating abroad? Currency swings become a permanent part of your budget. Our retirement savings calculator helps you size the nest egg, and running your target income through this converter shows what it really means in your new home currency.
