Be aware that currencies are stuck with rates from several years ago and don’t update.

I wonder if this could be addressed with periodic updates.

  I didn’t look too deep into it, my understanding was that the source it uses to update itself has been taken offline. There are workarounds involving data massaging and a cron but honestly that’s a lot more work than typing “1000 chf to usd” into ddg and getting the converted amount. But if you know something I don’t, maybe you could share for everyone’s benefit?

Looking at the source of the default configuration (cat /usr/share/misc/units.lib), I believe it only defines conversions for currencies that are pegged to another one (mainly to EUR or USD). You have: 10 franc You want: dollar conformability error 1.5244902 euro 1 usdollar You have: 10 franc You want: euro * 1.5244902 / 0.655957

I'm tempted to say it shouldn't even attempt to support currency conversion, as constantly in flux as it is.

Running `sudo units_cur` does the trick for me. $ units Currency exchange rates from FloatRates (USD base) on 2020-05-12 $ sudo units_cur $ units Currency exchange rates from FloatRates (USD base) on 2020-07-09 (GNU units, packed by Debian)
