There are only [DELETED-three-DELETED] four countries that do not use the metric system. One of them is a former British colony [1] that parted ways over some taxed tea, the second country [2] was formed from former nonvoluntary agrarian workers [3] from the former British colony that parted ways over some taxed tea, and the third … is surprising [4].
My friend Bibo commented on FaceGoogleMyBookPlusSpace, that growing up in the Bahamas [5], he remembered using the Imperial System [6] and not the metric system. And from some checking (granted, I only checked two [7] sites [8]) it appears they may still use the Imperial System.
I wonder if there are any more countries that don't use the Metric System?
