How to Use This Calculator
This converter multiplies your amount by an exchange rate you provide. It does not fetch live rates. Enter the amount, choose the two currencies, type the current rate, and it shows the converted amount plus the inverse rate for the reverse trip.
Enter the Amount and pick the From and To currencies. The β Swap button flips the pair and inverts the rate for you.
Type the Rate as "1 unit of From = X units of To." Click any pair in the common-pairs grid to load its starting estimate, then adjust it to the current rate.
Read the converted amount and the inverse rate. For real transfers, enter your provider\'s rate, not the search-engine mid-market rate.
Remember that banks and transfer services add a spread of 1 to 3 percent, so the amount you actually receive will be slightly less than a mid-market conversion.
The Currency Conversion Formula
Currency conversion is one multiplication, but the rate direction trips people up. A rate is always quoted as a pair: "1 USD = 0.92 EUR" means multiply dollars by 0.92. The reverse rate, "1 EUR = 1.087 USD," is simply 1 / 0.92. If you catch yourself dividing when you should multiply, check the units: dollars times (euros per dollar) leaves euros, which is what you want.
Worked Example
You have $100 and want euros. Enter amount 100, From USD, To EUR, rate 0.92. Converted = 100 x 0.92 = 92 EUR. The inverse rate is 1 / 0.92 = 1.087, meaning 1 EUR = $1.087. Now the realistic version: your transfer provider quotes 0.90 EUR per USD after its spread. Enter rate 0.90 instead: you receive 90 EUR, and the 2 EUR difference is the provider\'s cut, about 2.2 percent of the mid-market result.
Getting the Best Rate on Real Transfers
For amounts under a few hundred dollars, the differences between providers are small and convenience wins. Above $1,000, compare at least two specialist transfer services against your bank, because banks routinely charge the widest spreads. Avoid airport kiosks and hotel desks entirely; their rates are the worst in the business. Pay in the local currency when your card offers the choice ("pay in USD or euros?"), because the merchant\'s conversion rate is almost always worse than your card network\'s. And never trust a rate you saw yesterday: enter a fresh one for every conversion that matters.

Frequently Asked Questions
Does this converter use live exchange rates?
No, and that is deliberate. Live rate feeds require paid APIs, so this tool uses rates you enter yourself, with editable starting estimates for common pairs. The interbank rate also moves constantly during the day, so even a "live" number is stale within minutes. For any real transaction, check the current rate with your bank or transfer provider right before you convert.
How do I convert currency with a rate I enter?
Enter the amount, pick the From and To currencies, and type the rate as "1 unit of From equals X units of To." For example, with 100 USD, From = USD, To = EUR, and rate 0.92, the result is 100 x 0.92 = 92 EUR. The calculator also shows the inverse rate automatically.
What is the difference between the interbank rate and what I get?
The interbank (mid-market) rate is the wholesale price banks trade at with each other; consumers never get it. Banks, card networks, and money transfer services add a spread, typically 1 to 3 percent, and sometimes a flat fee on top. If the mid-market rate is 0.92 EUR per USD, your bank might give you 0.90, pocketing the difference.
How do I find the current rate for my conversion?
Search "1 USD to EUR" in any search engine for a mid-market reference, then check your actual provider, bank, card, or transfer service, because that is the rate that decides what you receive. Enter the provider's rate, not the search result, into this calculator if you want the true received amount.
Why do JPY and KRW amounts look so large?
Because those currencies are denominated in small units: one US dollar buys around 150 Japanese yen, so prices in the thousands are normal. The math is identical, only the scale differs. This converter handles the decimals for you, showing yen with no decimal places and most other currencies with two.
