A metric user might still forget to divide the diameter by two when calculating the area of a circle, but they are not going to, say, transpose the digits of the conversion factor between cm3 and litres because there aren't any digits to transpose. The one mistake that can be made due to the unit of measurement in metric is the number of 0s, and the error size when that happens is literally in the orders of magnitude scale, and thus trivially noticeable.

It is easier to notice you have spare zeroes over a 52.80 multiplier...
