I'm a graduate student in audiology, and we express middle ear pressure in daPa (decaPascals). Go figure.

I've lived in the US my entire life, but I try to think in meters because I seem to make more mistakes when I'm having to deal with things like eighths of an inch than when everything is just base 10--metric is so much easier! I do tend to think inches when sewing, though, since all of my good rulers and cutting mats only have inches marked. The interstate I take to my parents' house is marked in kilometers because it only exists between Tucson and the border with Mexico, and I still have no concept of how long a km is... I just know it goes by faster than a mile does.
