Metric vs. other measurement systems - chart

[marksbug]

so..how many cubic millimeaters is road island??
I wasent aware that inches is the official american mesurement...how can that be??so why are my american cars metrick?I alsent aware that i have to stop deviding metric...I thought 16 mm divided by 2 was 8 mm...I must be missing something... I think that it may just be a week brain that cant seem to make either or both work. do i have to get permission from the math gods to replace the tiny metric lifters in my ac vw engine with big jessell 7/8" roller lifters?? will the earth spin off it's axsess??? is the earth flat when measured with the metric system?? what about the moon?? it is cheddar in inches and swiss cheezze in the metrick system??**** I better go back to school, this new math is really centrifuging me. sorry for the spelling part it is is now in metric.
