Currency Converter
Convert between 160+ world currencies using daily mid-market reference rates.
Rates come from a free public foreign exchange API and are cached in your browser for 30 minutes. They are market mid-rates, so the rate your bank or card issuer gives you will be slightly worse once their markup and fees are applied.
How this currency converter fetches, caches, and applies live foreign exchange rates
This tool pulls real exchange rates from open.er-api.com, a free public foreign exchange API that needs no key or account. It is not a static table with numbers frozen at the time this page was built. One request returns the rate of every supported currency against the US dollar, and every pair you pick is worked out from that single table.
The request and cache cycle
The provider publishes new reference rates once a day, so there is no point calling it on every keystroke. The tool fetches once, keeps the table in your browser, and does the rest with arithmetic.
localStorage for a saved rate table. If it is less than 30 minutes old, it is used directly with no network call.
open.er-api.com/v6/latest/USD, which returns every supported currency's rate against the dollar in a single response, along with the provider's publish time.
Worked example, using representative rates: if 1 USD buys 0.92 EUR and 84 INR, then converting 500 EUR to INR uses a rate of 84 divided by 0.92, about 91.30, so 500 EUR is about 45,652 INR. The tool also shows the same amount in the other popular currencies at once, USD, EUR, GBP, JPY, INR, AUD, CAD, CHF, CNY, AED and SGD, all from the same table.

Interface details worth knowing
Quick currency buttons and live results
The result updates as you type or change a currency. A row of shortcut buttons sets the target currency in one click, and Swap reverses the pair.
Manual refresh and copy
Refresh Rates fetches a new table straight away. Copy Result puts the amount, the converted figure and the rate date on your clipboard. The rate line also shows the reverse rate.
If the number looks off
Amounts are shown with each currency's normal number of decimals, none for yen, won or Vietnamese dong, two for most currencies and three for dinars such as the Kuwaiti dinar. Very small results show four significant digits so they never round to zero.
Exchange rates shown here are for reference and estimation only, not a quote you can transact at, and not financial advice.

FAQ: Currency Converter
The data provider publishes new reference rates once a day. This tool keeps the rate table in your browser for 30 minutes after each fetch to avoid unnecessary requests, and the publish time is shown above the converter. You can fetch again at any time with the Refresh Rates button under the result.
This converter shows the interbank mid-market rate, the raw rate banks use when trading currency with each other, with no markup added. Banks, card networks, and money transfer services almost always add a margin on top of this rate, often 2% to 5% or more, plus sometimes a flat fee. The mid-market rate is useful as a fair, neutral benchmark to compare how competitive a bank or service's actual offered rate is.
The tool supports over 160 currencies and territories, essentially every active ISO 4217 currency code tracked by the data provider, including all major world currencies as well as many less common ones. The dropdown menus populate directly from the live data feed, so the list stays current if currencies are added or retired.
No, this tool covers fiat currencies (government issued currencies like the US Dollar, Euro, and Japanese Yen) only. Cryptocurrency prices move on separate exchanges with far higher volatility and require a dedicated crypto price feed, which this tool does not pull from.
Use this converter to estimate value and compare providers, not as the exact rate you will be charged. For an actual transfer, always check the live quoted rate directly from your bank, card issuer, or transfer service at the time of the transaction, since rates move continuously and every provider applies its own margin on top of the mid-market rate shown here.
Caching for 30 minutes reduces the number of requests sent to the exchange rate API, which keeps the tool fast, reliable, and within the free usage limits of the underlying data provider. Since the provider only publishes new rates once a day, the cached table is as current as a fresh fetch would be.
If the live data feed cannot be reached, the tool falls back to the last rate table saved in your browser and tells you clearly which date those rates are from. If nothing has been saved yet, it shows an error and asks you to try again, rather than showing an estimated figure.
No. The only things stored, and only in your own browser, are the general exchange rate table and the last currency pair you picked, so the tool reopens where you left it. The amounts and currencies you convert are never sent anywhere beyond the public rate lookup itself, and no conversion history is logged.
