whatever floats your boat, but it sounds a bit overkill to me.
As a european, I notice how imperial units are sometimes creeping back in. Even hating the crappy illogical mess, you learn to get some feeling just by exposure. Feet divided by 3 is about a meter, and 4 inch is 10cm. A mile is 1.5km.
For some reason I can remember pounds as 1/2 kg, but can never figure out lb without looking it up and finding it is also pounds.
A while ago, a local computer store mixed up feet and inch, and announced things like 14 feet laptop screens. I was the first to tell them, the mistake had been there for a month. It turns out non-USians know what a screen of size 14 is supposed to look like, and the word 'inch' behind it is treated like meaningless gibberish.
