About Currency Converter
Converts between 16 common currencies using built-in fixed reference rates, computed entirely offline. The rates do not track the market and are not presented as live — check a bank or market site for actual rates.
- 1
Sixteen common currencies on fixed rates against USD; converting A to B uses target rate divided by source rate, computed entirely offline.
- 2
A notice sits permanently above the result: these are fixed reference rates that do not track the market, and no "last updated" date is claimed — inventing one would be worse than omitting it.
- 3
Both unit rates are shown (1 A = ? B and 1 B = ? A), so you can sanity-check the magnitude rather than trusting a single total.

Decimals are fine; leaving it empty counts as zero.

The arrow between them swaps both at once.

The large figure is the converted amount; two unit rates sit below.
These are fixed reference rates that never move, while banks quote a live mid-market rate plus a spread. The two should not match, and the gap changes over time and by currency pair.
No. It is fine for estimating travel budgets or checking magnitudes; use a bank or market site for anything involving real money.
Live rates require network calls and a third-party service, which brings availability, quota and "who sees the request" questions. The only networked tool here is the IP lookup, and a second one deserves its own decision.
