Another science nerd here. I find that my brain handles kilograms and celcius just fine at work. The instant I walk out the door, it flips back to lbs and F.

The boyfriend is Canadian; he flips between km and miles like it's nothing, whereas I have difficulty with kilometers father than I can bike. When he told me something was 300k away, I squinted for a second and admitted "ok, one more time in real numbers...?"

I still think of everything pressure in PSI, though. 3 bar doesn't sound like a lot, but eeeesh.

-- gnat!
