Metric makes mistakes easier. I have never noticed that metric makes arithmetic easier. I have noticed that it makes not a bit of difference for practical purposes.

I guess it depends on what math you do - because with metric measurments you use powers of 10. Its a lot easier to for me to divide by 10 than by 12, for example.
