This brief Rochester (NY) summer, I had a chance to visit a few swimming pools. Without an exception all were marked in feet and inches without a sign of a metric equivalent. Likewise, all had the words "feet" and "inches" spelled out, which is quite a bit of mosaic work. It's pretty obvious, that when building a pool, writing "1.25 m" is a lot more cost effective than "4 feet 2 inches" at 5 characters vs. 12. Likewise, quite a bit of space is saved.
