I was going to post this question in the 40 min. mile thread, but thought it might be too much of a diversion. But the mention of 1600 m. as a mile gave rise to my question. How does 1600 meters compare to, say, 1800 yards distance-wise? I've always used 1800 as my measure of a mile, since it wouldn't be too practical to stop 10 yards into the lap after 1760. ;)
I've also heard people refer to 1650 yards as a "pool mile." So now I have to admit I'm a little confused as to what in fact is universally accepted as a mile and what mile measure then applies to open water. I don't mind "erring" on the longer side, since if it's shorter than I think, I'll suddenly be faster! :D
