- Results are only as accurate as your inputs — double-check units, since mixing metric and imperial is a common source of error.

Frequently Asked Questions
How current are the exchange rates used in this converter?
Rates are refreshed regularly from aggregated mid-market sources. For large financial transactions, always confirm with your bank or broker, as live interbank rates differ from retail rates you receive.
What is the difference between mid-market rate and the rate my bank gives me?
The mid-market rate is the midpoint between buy and sell prices on the global currency market. Banks and exchange services add a spread or fee on top of this rate. The rate shown here is mid-market — your bank's rate will be slightly less favorable.
Can I convert between crypto and fiat currencies here?
This converter focuses on traditional fiat currencies (USD, EUR, GBP, etc.) sourced from central bank and market data. Cryptocurrency pairs are not included due to their high volatility and the need for real-time exchange feeds.
Why might my converted amount differ from what a money transfer service shows?
Money transfer services add fees and use proprietary exchange rates that include a margin. The rate shown here is the mid-market reference rate. To find the true cost of a transfer, subtract the service fee from the converted amount and compare.
How do I convert an amount to multiple currencies at once?
Change the To currency and note the result, then change To again for the next currency. For bulk conversions across many currencies, a spreadsheet linked to a rates API is more practical — this tool is optimised for quick single-pair lookups.
Which currencies does the Currency Converter support?
The Currency Converter supports 30+ world currencies including dollar, euro, pound, yen, yuan, rupee, and more. All conversions use live exchange rates so you always get the current value.
