About Currency Converter
The Currency Converter converts between 35+ world currencies — US Dollar, Euro, British Pound, Indian Rupee, Japanese Yen and more — using exchange rates refreshed daily from free, public rate sources.
Rates are cached in your browser for 24 hours, so repeat conversions are instant and the tool keeps working even if the rate service is briefly unreachable. When only older cached or bundled rates are available, a clear 'stale rates' badge tells you the numbers may be out of date.
Conversions use mid-market rates, which are ideal for estimates and comparisons. Banks and card networks add their own margin, so the amount you're actually charged may differ slightly.

Frequently Asked Questions
