I know [too many] Canadians who have been fuelling their autos
with litres of gasoline for decades; they have been reading SI road maps
and SI road signs and reading SI speedometers and odometers for
decades.
YET, they STILL check their fuel usage in miles per
gallon!
The missing link in their thought process is that they have
not established a few bench-mark numbers such as (say) 10 L/100 km for a
reasonably thrifty vehicle (14 L/100 km corresponds to the old 20
miles-per-gallon).
Once they do that, the rest is easy.
The same thing goes for weight-watchers. Instead of
reading weight in kg and traslating it back into FFU for comparison to (say) 130
lbs. (their desired weight - sorry Prof. M. -), they fail to
translate the 130 (or whatever) into 60 kg and base their action at the table on
their most recent kilogram readings.
If they cannot relate to (say) 15 cm of snow, they should
obtain a metre-stick and, every once in a while, have a good LOOK at it.
See where 10 cm, 20 cm, 50 cm etc. come on the stick. Also have a look at
the small divisions to see that a millimetre is about the thickness of a thin
dime.
