Quote - > Quote - ...When I went to school it was always feet and inches.

We also worked in pints and gallons, not litres.
I even look at the Farenheit side of my thermometer, not Centigrade...

Since I'm in the U.S., I automatically comprehend measurements in feet, inches, etc. It is so ingrained in me that I perceive those measurements based on visual associations.

If you say "6 ft.", for instance, I immediately think of the height of my father.

It's only when something is told to me in meters or litres that I have to do mental calcuations. :P

That's exactly how I am.   I can visually percieve things in imperial but not metric, though I know 1 m is just under 1 yd but that's all.

If I know I'm going somewhere that's 10 miles away - I know jsut how far that is and roughly, traffic permitting, how long it'd take me.  If someone said 'It's 10 kilometers away'......well, I just wouldn't have a clue.

I've not been in any job where metric knowlege is important so why change ?

I make cakes using ounces not grammes and they come out lovely, fluffy and light
