Made this very simple command-line crypto calculator/conversion utility.
If you've got NodeJS installed you can install with "npm i -g calq".

It supports very similar queries to these you might put into google.
Say "10 ETH to EUR". (but unlike google supports more cryptos and is a little more forgiving).

Hope you find it useful.
