I am reading (yet another) Swedish detective novel translated into English at the moment, and I find that I'm thrown by some of the translation.

As you might guess, it's to do with the translation of the units of measurement from metric (I assume, but I'll get back to that) to imperial. First thing is, I have taken to the metric system like a duck to water, and faced with an imperial measurement like 3 feet, I will automatically convert it back to metric. And, efficient person that I sometimes am, I regret the time that the translator spent that I just had to undo.
