How it works
A currency converter calculates how much one currency is worth in another by multiplying the amount by the exchange rate. This calculator supports 15 major currencies with daily reference rates and an optional custom rate.
- Enter an amount
Pick the currency you are converting from.
- Pick the target currency
Use the swap button to flip the two currencies.
- Read the conversion
The daily reference rate updates once a day. Override it any time with your own rate.
How exchange rates work
Exchange rates represent how much one currency is worth in terms of another. They move constantly with supply and demand in the foreign exchange market, influenced by interest rates, inflation, political stability, and economic data.
Converted amount = original amount × exchange rate
For example, 1,000 USD at a rate of 0.92 converts to 920 EUR. The inverse rate, 1 divided by the rate, converts back the other way: 920 EUR at a rate of 1.0870 converts to about 1,000 USD.
Bid, ask and mid-market rates
- Mid-market rate: the reference rate midway between buy and sell prices. This calculator shows Exchange Rate-API daily reference rates; banks and cards may quote different rates and fees. Rates By Exchange Rate API.
- Bid rate: what a bank pays you when you sell it foreign currency.
- Ask rate: what a bank charges you when you buy foreign currency from it.
- Spread: the gap between bid and ask. Compare the actual exchange rate and all quoted fees for your provider.
Getting a better rate
- Avoid airport exchanges: compare the actual exchange rate and all quoted fees for your provider.
- Use a local ATM abroad: often better than exchanging cash, though check for foreign transaction fees first.
- Pay in local currency: when given the choice at a card terminal, compare the offered conversion rate and fees with your card issuer's local-currency conversion terms.
- Compare services: banks, card issuers and transfer services quote different rates and fees for the same pair.
Before you rely on the rate

Frequently asked questions
How does the currency conversion formula work?
Converted amount equals the original amount times the exchange rate. The exchange rate expresses how many units of the target currency equal one unit of the source currency. The calculator also shows the inverse rate, 1 divided by the rate, so you can convert in either direction.
Which currencies does this converter support?
The calculator supports 15 currencies: USD, EUR, GBP, JPY, CNY, KRW, CAD, AUD, CHF, HKD, SGD, INR, MXN, BRL and NZD. A custom rate overrides the rate for the selected pair; the selectors support only the 15 listed currencies.
Are the exchange rates daily reference rates or custom rates?
The calculator fetches Exchange Rate-API daily reference rates and caches them for 24 hours. It shows the provider update date in UTC. If a fetch fails, it uses the last successful provider rates with their original update date; without those, enter a custom rate. Banks, cards and transfer services may quote different rates and fees.
What is the inverse rate and how do I use it?
The inverse rate is 1 divided by the displayed exchange rate. If 1 USD equals 1.09 EUR, the inverse rate is about 0.917, meaning 1 EUR equals about 0.917 USD. The calculator shows this automatically, so you can check both directions of a pair without re-entering inputs.
Can I use this calculator to plan cash for a trip?
Yes. The quick reference table shows converted amounts at common quantities from 1 to 1,000 units. Compare the actual exchange rate and all quoted fees for your provider.
