I got tired of switching between Alfred's calculator and currency converter, so I've created this monstrosity.
This is a currency converter with fully-featured built-in calculator and flexible syntax. It is written in Golang, so it feels very responsive once the conversion rate is downloaded.
Full readme is availible at github, workflow file is included in the release.
This project uses currencyconverterapi.com for rate information, you have to get a free API key from them
