Did you know that there are still people in this world who use imperial units? For some reason they refuse to switch and continue using this stupid system. I requent Reddit and it's quite common to find these people there, so instead of just bitching I decided to do something about it.

I have made this Safari Extension Units, Download

It takes common expressions as He is 5'4" tall and translates them to He is 5'4" (162.56 cm) tall, so now you know that he is quite short.

It can also convert some other units, such as miles to km, mpg to km/l and lbs to kg. Of course it does have limitations, for example if somebody writes He is 6 feet tall or He is 200 it does not get translated, maybe I'll add it later, or if somebody wants to contribute, you're more than welcome.

I've switched from Safari back to Chrome recently, so might be I port it there as well, when I get sufficiently annoyed again.
