How is wolfram alpha? I always use it for more complicated pure math, but I don't think I ever used it for unit conversion.

  It's great at unit conversions. You can do things like "number of milliseconds between amsterdam and paris at speed of sound". I use it all the time.

    Your query doesn't exactly work though, it's interpreted as "paris at speed of sound". However "time between amsterdam and paris at the speed of sound in milliseconds" does work, returning 1.26*10^6 ms.

      (shame smiley) I could've tested the query, but I wrote it on mobile.

        Hahah, I was also on mobile. The mobile website of Wolfram Alpha works pretty good, they also have an app but haven't tried it yet.
