I dunno I learned the "BRITISH SYSTEM" in grade school but being a mechanical engineering student ive become fairly comfortable with both only thing i still have trouble with is Celsius to Farieheit or vice versa but hey we all look at our engines power in Hp for the most part and thats british too so maybe some of u should just be more open minded, and learn to use both systems. Before nebody tries to make me feel stoopid yes i realize that engine Power is measure in other units as well just cant remeber them off the top of my head. just my thought on the matter
