There's a direct cost in money, time and lives that has come from the US's adherence to their US Customary Units (which are often different to the old imperial units). People have literally died because of the confusion caused by having multiple systems of units in common use with ambiguous names (degrees, gallons, etc). Each year industry worldwide spends an enormous amount of money indirectly precisely because of this problem and it's still incredibly unlikely to be fixed within my lifetime. Bash-alternatives that are not completely compatible frankly just don't have a chance.
