About the Currency Converter
Converts an amount between currencies using exchange rates fetched live from a public rates source each time the page loads, with fixed fallback rates if that service is unreachable.
How to use it
- Choose the From and To currencies.
- Enter an Amount.
- Read the converted result, and check the status line for whether rates are live or fallback.
Formula
Converted amount = (Amount ÷ rate of source currency) × rate of target currency, both expressed relative to a common base currency
Worked example
At a sample rate of roughly 0.92 EUR per USD, converting $100 gives about €92.
Recommendations
- • Rates move throughout the day — refresh right before making a decision if timing matters.
- • For travel budgeting, add a buffer over the displayed rate, since card networks and exchange counters apply their own margin.
- • Bookmark a specific pair you track often rather than re-selecting it every visit.
Frequently asked questions
Rates refresh from a live source on every page load. If that source can't be reached, the tool falls back to fixed sample rates and tells you so.
