Currency Converter
Convert an amount from one currency to another and see the rate in both directions. The built-in table holds sample rates from early 2025 — for anything real, type the current rate into the override box instead.
Example rates as of early 2025, rounded — not live rates. For practice only: check a bank or an authoritative source for the current rate before any real transaction.
Formula and calculation
Worked example
Converting $100 at the built-in sample rate of 0.96 euros per dollar gives 96. The rate is 0.96 and the reverse rate is 1.0417, so 100 euros is about $104.17 at the same rate.
Why this page shows sample rates, not live ones
Exchange rates move every second, and this page does not pretend otherwise: it is a static table of rounded early-2025 values, labelled as such wherever it appears. Real-time rates need a data feed, and a number that looks live but is hours old is worse than one that admits its date. So the page does two honest things — it shows the sample table so you can practise conversions and sanity-check orders of magnitude, and it gives you an override box for the rate you actually got from a bank, a card statement or a central bank. Nothing here executes a trade, so a stale rate cannot cost you money; treating the sample rate as a quote could.
What actually moves an exchange rate
Interest rates are the biggest driver: when a central bank raises rates, holding that currency pays more, and demand usually lifts it. Inflation pulls the other way, and trade flows, government debt and political risk all feed in. That is why a rate from last month, last week or even this morning can be far from the rate you get at the counter. Banks and card networks also add a spread of roughly 0.5% to 3% on top of the mid-market rate, plus fixed fees on small transfers — so the number that matters for your wallet is never the headline one. Treat any single rate as a snapshot of a moving target.
What the results mean
- Converted amount
- Your amount in the target currency, using the built-in sample rate or the rate you typed in.
- Exchange rate
- How much of the target currency one unit of the source currency buys. Cross rates are built from the US dollar rates in the built-in table, so no pair is missing.
- Reverse rate
- The same exchange rate the other way round: one unit of the target currency in the source currency. Multiply by this to convert back.
- Rate used
- Where the rate came from — the built-in early-2025 sample table or your own entry — and the reminder to verify before a real transaction.
Frequently asked questions
How current are the exchange rates on this page?
They are rounded sample rates from early 2025, not live quotes — the table header and the result note both say so. For practice, planning and order-of-magnitude checks they are fine. For anything that moves real money, type the rate you were actually quoted into the override box, so the calculation uses your number rather than ours.
Where do I find the real exchange rate right now?
Central banks publish free reference rates — the European Central Bank around 16:00 CET on working days and the Federal Reserve's H.10 release each week — and currency sites such as xe.com publish mid-market rates continuously. Your bank or card issuer shows the rate you will actually get, which includes their markup. Compare the two before a large transfer.
How do I convert an amount by hand?
Multiply by the rate when the rate is quoted as target units per source unit: 100 dollars at 0.96 euros per dollar is 96 euros. Divide when it is quoted the other way: 96 euros ÷ 0.96 = 100 dollars. The Reverse rate on this page saves you flipping the division, and the quick table lists common amounts already converted.
Why is my bank's rate worse than the one I see online?
Because the online figure is the mid-market rate — halfway between what buyers and sellers are paying — and no bank deals at that price. Card networks and banks add a margin that commonly runs from about 0.5% to 3%, transfers add a fixed fee, and some quote different buy and sell rates. A rate that looks a few percent off is normal; a rate that looks wildly off usually means a stale page or the wrong currency pair.
Which currencies are covered, and what if mine is missing?
The built-in table covers 32 widely used currencies, from the US dollar and the euro to the Vietnamese dong and the Argentine peso. Anything outside that list still works through the override box: look up the rate you need, type it in, and the conversion, the reverse rate and the quick table all follow your number. The same trick handles historical rates — enter the rate from the date you care about.
