Saw the movie U-571 on video last night, which incidentally is pretty good WWII sub movie. Without getting into detail, and American sub crew is sent out to capture a Nazi U-boat, so as to grab a working Enigma machine. In the process they wind up commandeering the U-boat and sailing it away, and in the process have to read all the depths gauges in meters. They seem to do so with ease, and don't make a big deal of it. It's a good movie. Nat
