How did the US standard system of measurement develop?

Answer 1

It is a copy of the obsolete English measurement system, a colonial fossil.

Answer 2

Because it existed long before the new-fangled Metric system was even invented,

and by gosh, if it was good enough for the Pilgrims, then it ought to be good enough

for us, without trying to confuse everybody with the complicated Metric system and

all of its weird units. If the good lord had meant for us to use the Metric system,

He would have given us ten fingers.

Answer 3

The decimal system now mostly in use worldwide was created by the French Emperor Napoleon, who made it the standard in all the European countries that he controlled directly or indirectly.
