How to use the Currency

Type the amount you want to convert, choose the currency you have in From and the currency you want in To. The converted amount and the exchange rate in both directions update instantly. Use the swap button to reverse the pair.

Rates are mid-market reference rates covering 150+ currencies, loaded from a free public feed that refreshes about once a day. The time of the latest update is shown under the result. The last good set of rates is saved in your browser, so the converter still works if you go offline — it will tell you when it is showing saved rates.

Banks, card issuers and exchange bureaus usually add a margin or fee on top of the mid-market rate, so the amount you actually receive will normally be somewhat lower. Use this tool for estimates and price comparisons, not for executing trades.

Formula

All rates are quoted against the US dollar, so any pair is converted through USD:

Converted = Amount × (Rateto ÷ Ratefrom)

For example, if 1 USD = 0.92 EUR and 1 USD = 0.79 GBP, then 1 EUR = 0.79 ÷ 0.92 ≈ 0.859 GBP.

Frequently asked questions

What exchange rate does this currency converter use?

It uses mid-market reference rates — the midpoint between the buy and sell prices on global currency markets — from a free public exchange-rate feed. This is the same kind of rate you see on financial news sites and search engines.

How often are the exchange rates updated?

The feed is refreshed roughly once a day. The converter shows the time the rates were last updated, and fetches fresh rates each time you open the page. If it cannot connect, it falls back to the last rates saved in your browser and tells you so.

Why is the rate from my bank different?

Banks, card networks, airports and money-transfer services usually add a markup (the spread) to the mid-market rate and may charge a fixed fee as well. Comparing their quote with the mid-market rate shown here tells you how much the conversion is really costing you.

Does the converter work offline?

Yes, once you have loaded it at least once with an internet connection. The last successful set of rates is stored in your browser and is used automatically when you are offline, with the date of those rates displayed.

Can I use these rates for taxes or accounting?

They are fine for estimates, but tax authorities and auditors often require a specific official rate — for example a central bank rate or the IRS yearly average rates. Check which source you are required to use.

Understanding Exchange Rates

Exchange rates fluctuate based on supply and demand, influenced by interest rate differentials, inflation, trade balances, and geopolitical events. The "mid-market rate" (the midpoint between buy and sell prices) is the fairest rate. Banks and exchange services add a markup — always compare the offered rate to the mid-market rate to understand the true fee.
