It does induce a geeky joy but it's ephemeral for the most part as Google is vastly superior in usefulness. I learned about units few years back, used it for a while, and I can't even remember when but I just started Googling the conversions instead of switching to the terminal window.

I mostly use Spotlight (on OS X) to do conversions since it saves me switching to the browser or terminal. It doesn't handle as advanced conversions as Google does but it handles 90% of my common cases (including currencies)

Damn, I didn't know Spotlight could do this. Thanks!

I don't think Google can convert millilightseconds to miles at one go. The units program has support for much more esoteric units than Google does.

It doesn't understand millilightseconds, so you need https://encrypted.google.com/search?q=%283+milliseconds+*+sp... or https://encrypted.google.com/search?q=3+light+seconds+%2F+10...
