Good progress! 

If you know more JavaScript, then following improvements would be great idea:

By default
- show the full table with all currencies as you did originally (since that's nice to see as a first thing)
- set initial "units" value to be 1 automatically. 
- let user input the "Units" and as soon as user inputs the number it could recompute the whole table automatically - that would be cool and visual. 
- then if user wants to select specific currency, then yes, maybe filter down just to that single row. 

Also
- It would be good to do smart formatting of the numbers, e.g. instead of `21962.86467679295` sats you could do `21'962.9` sats (since more decimal places don't make sense anyway)
- it would be also good idea to have a solid scheme in the URL, e.g. sats2fiat.html?u=123&f=eur (so the specific value can be shared with someone)




updated to do the reverse conversion too...   i.e from fiat  to sats

Fiat to Sats converter

It would be good if I can actually input the amount of currency and maybe even pin the currencies I'm interested in (e.g. store that setting in localStorage).
