conversion to the metric system

Most countries in the world use the metric system,but we dont the United states dont.It would be way easier for everybody if we started using the metric system to measure thing and weight thinngs.No more pounds,inches, now its time for kilograms,centi-meters.It would be much easier for tourist and everybody that came to the us to know how everything is.also when we go to other countries we wouldnt be that confused with there measurments and everything else.
