The formula
converted = amount × (USD rate of target ÷ USD rate of source)
How it works
Each currency has a rate against the US dollar. The tool converts the amount to USD, then from USD into the target currency, giving the converted amount and the direct exchange rate.
Where it is used
- Quick conversions for travel or online shopping
- Comparing prices quoted in different currencies
- Checking the cross-rate between two non-USD currencies
Worked example
Converting $1,000.00 from USD to AUD gives … at an exchange rate of ….
Enter an amount, the currency you are converting from and the currency you are converting to. This currency converter returns the converted amount, the direct exchange rate between the two currencies, and the value in US dollars as a reference. It is useful when booking travel, shopping on an overseas site or comparing prices quoted in different currencies.
How the converter works
Each currency has a stored rate against the US dollar. The converter changes your amount into dollars and then into the target currency, which gives both the result and the rate between your two currencies. Because everything goes through the dollar, it can handle any pair it supports, even currencies rarely quoted against each other.
Cross rates
A rate between two currencies worked out through a third is a cross rate, and most currency pairs in daily life are worked out through the dollar. If you often deal with the same pair, knowing the rate helps you judge quickly whether a price is reasonable.
The dollar reference
The dollar is the world's most widely used reference currency, so the dollar value gives a common anchor for comparing offers across countries without doing the arithmetic yourself.
Reference rate versus what you pay
The converter shows a reference rate. When you actually exchange money through a bank, card network or exchange service, a margin and sometimes a fee are added, so you usually receive a little less. Use the converter for a fair estimate, to compare prices in different currencies, and to check a quote before you commit; when the exact amount matters, check your provider's rate and fees.
Market rates move throughout the trading day. The stored rates are maintained and updated, but they are not a live feed, so for a large or time-sensitive transaction confirm the rate at the moment you transact.
Getting better value when you exchange
Compare what you actually receive, not just the advertised rate: one provider may add a fee while another builds its margin into the rate. A zero-commission offer can still carry a cost in the exchange rate. When a card terminal abroad offers to charge you in your home currency, the rate it uses is often worse than letting the payment settle in the local currency. Checking the converter first gives you a benchmark for spotting a padded quote.
