Important disclaimer
Currency results use stored manual exchange rates and are estimates only. Update the `currency_rates` table before using this page for important financial decisions.
Currency Converter helps with financial planning by using Amount to convert, Convert from, Convert to, and Decimal places to calculate Converted amount, Exchange rate, Rate date, and Rate source. It includes a visible formula, readable result summary, and export-ready details.
This converter does not call a paid exchange-rate API. It reads manually stored rates from MySQL and shows the rate date and source in the result panel.
- Enter the amount you want to convert.
- Select the source and target currencies.
- Check the stored rate date before using the estimate.
- Use Swap to reverse the conversion quickly.
converted amount = amount x (target rate from USD / source rate from USD)Where do exchange rates come from?
Rates come from the local MySQL currency_rates table and are intended for manual updates.
Can rates become stale?
Yes. The calculator shows a warning when stored rates are older than the freshness window.
Does this use a paid API?
No. It avoids paid APIs and uses locally stored rate data.
