100 USD to SAR          ->   375.00 SAR   (one-off conversion)
$15 + €5 + 20 JOD       ->   works with symbols too

Run

Requires Python 3.9+ on Windows (standard library only, nothing to install). Double-click currency_calc.pyw.

Build a standalone .exe

Double-click build_exe.bat. The app is created at dist\CurrencyCalc.exe.

Rates

Rates come from open.er-api.com, with a backup from fawazahmed0/currency-api. They are mid-market rates, so they will be slightly better than what a bank or exchange office charges. Gold and silver spot prices come from gold-api.com and refresh every 5 minutes.

Your data

Settings, history and cached rates are stored in %APPDATA%\CurrencyCalc (not in this folder).

Version

See the version history at the top of currency_calc.pyw. Current: 1.8.0
