For the same reason there are many different languages. Each culture developed their own system independent of any effects from other cultures. History.
These days it doesn't matter. Modern CNC machines don't care about units. In the older machines one complete turn of a lead screw moved something a finite unit of measure and it was always difficult to convert Metric to Inch on machine tools. Today's machines don't care, they count encoder pulses.
