Just before Christmas, someone showed me how to use Google (yes… the search engine) to convert values between units (e.g. kilometres into miles). I didn’t know that feature was there in Google and it turns out there are many more useful search features too – things like the weather forecast, films at the local cinema, etc. (as well as the well known stuff like definitions, inbound links and Google’s cache).
