Frequently Asked Questions
About This Calculator
Exchange rate tables are published against a single base currency, so converting between two other currencies means a cross-rate: divide the target currency's rate by the source currency's rate, both quoted against that base. The number that comes out is a mid-market rate, the midpoint between what buyers bid and sellers ask, and it is a reference point rather than a price anyone is offered at retail.
A same-origin PHP endpoint on this site fetches USD-based rates from a public feed and caches them for an hour, and your browser keeps its own copy in local storage for the same period, so one visitor's refresh serves the next. The conversion itself is that cross-rate multiplication, done in the page. Amounts display to two decimals, and the rate line to two, four or six digits depending on its size.
Notes & Limits
- These are mid-market reference rates. Banks, card networks and transfer services apply their own spread and fees, so the amount you are charged will differ.
- Rates are cached for up to an hour on the server and another hour in your browser, and the feed itself updates about daily, so this is not a live market feed.
- Every amount displays two decimal places, including currencies normally quoted without minor units, such as the Japanese yen and the Korean won.
- All pairs are derived through USD as the base, and a currency with no entry in the built-in name list appears as its bare three-letter code.
