Dear Google, haven't you missed a 1.6?
translate.google.com
translate.google.com
http://translate.google.com/#auto/en/combien%20de%20kilom%C3...
But works with yards too! (including French)
http://translate.google.com/#auto/fr/how%20many%20yards%3F
I now want to make a table recording correct/incorrect translations between the metric system and the imperial system! This is going to be an unproductive day.
EDIT: it even works in Spanish if you forget the accent on "kilometros" http://translate.google.com/#auto/en/cuantos%20kilometros%3F
Why is that in reply to my own previous comment? I cannot see how this is "replying" (maybe you intended to post a regular comment).
