How It Works
Enter Amount
Type the amount you want to convert into the From input. Decimals are supported (e.g. 49.95). The conversion runs live as you type. Large amounts (millions or billions) are formatted with thousand separators in the All Conversions panel for readability.
Pick Currencies
Choose your source currency and target currency from the two dropdowns. We support 20+ major world currencies. Use the swap button between the panels to flip directions instantly — useful for double-checking a quote you got from a bank or travel agent.
Read the Live Rate
The Rate Info line below the result shows the exact exchange rate used and the date the rate was published. Rates come from the European Central Bank reference rates and update daily on weekdays. The Popular Conversions grid shows your amount in major currencies at a glance.
Currency Converter Features
Live Daily Rates
Exchange rates are fetched from the open exchangerate.host API, which sources data from the European Central Bank and other major central banks. Rates update once per business day around 16:00 CET. The page caches the rate for the session so repeated conversions are instant.
20+ World Currencies
All major reserve and trade currencies: USD, EUR, GBP, JPY, CNY, INR, CAD, AUD, CHF, HKD, SGD, NZD, SEK, NOK, MXN, BRL, ZAR, KRW, AED, SAR. Together these cover >95% of global FX trading volume.
Cross-Rates
All conversions are routed through EUR (the API base) and then to the target — this is the same way bank cross-rates are calculated. So JPY → INR is computed as JPY → EUR → INR with a single multiplication, giving the same result a forex desk would quote.
Live Conversion
The result updates instantly as you type. No "Convert" button to press. The Popular Conversions grid below shows your amount in 8 of the most-traded currencies at once, so you can see at a glance whether 100 USD is closer to 90 EUR or 90 GBP.
Mid-Market Rates
These are interbank mid-market rates — the same rate you see on Google Finance or Reuters. Banks and currency exchanges add a markup (usually 0.5%–4%) on top of this rate when you actually exchange money. Use this tool to know whether your bank is giving you a fair deal.
Privacy First
Only the rate table is fetched from a third-party API. The amounts you type are never sent anywhere — all multiplication happens in your browser. Safe for converting sensitive financial figures (salary negotiations, investment amounts, tax calculations).

Frequently Asked Questions
The European Central Bank publishes reference rates once per business day at around 16:00 CET. Our converter fetches the latest published rates when you load the page, so a refresh after 16:00 CET on a weekday will give you that day's rate. On weekends and bank holidays, the most recent business day rate is used.
Banks and currency exchanges add a margin (typically 0.5%–4%) on top of the mid-market rate to cover their costs and profit. Branch exchanges, airport kiosks, and credit-card foreign transactions usually charge the highest margins. Specialist services like Wise, Revolut, or interbank-rate cards charge much less. Compare the bank's rate to the mid-market rate shown here to see how much margin you are paying.
For estimates and personal use, yes. For accounting, tax filing, or contracts, you should always use the official rate published by your country's tax authority or central bank for the exact date of the transaction. We display the rate date used so you can verify against the official source.
We only include fiat currencies issued by central banks. Cryptocurrencies (BTC, ETH, etc.), commodity prices (gold, silver), and exotic emerging-market currencies are out of scope. If you need crypto conversion, services like CoinGecko or CoinMarketCap are more appropriate.
The exchange rate table needs a one-time network call when the page loads. Once the rates are fetched, all conversion math runs locally and you can keep using the tool offline for the rest of your session. If you load the page with no network, the converter falls back to a recent cached rate set with a clear warning.
