It's frustrating that the same people who push weird systems (ounces, the old money in UK) instead of metric units and decimal money are comfortable doing all kinds of mental arithmetic, but freeze when as soon as you involve a decimal point.
People who have no trouble with the concept of "half of a third for four people taken out of this bag of potatoes" get stuck on "0.25".
For all the people who answered my post - I agree that metric and SI are the sensible way forward. I'm kind of relieved that some sections of US[1] industry are choosing to ignore the international market or to lumber themselves with extra costs for both systems.
[1] Because I'm not in the US; I'm European and I want our industry to do well.
