Dear John,

In Australia, all timber is sawn, dressed, and sold in millimetres. For
example, you might buy a 2400�mm piece of 90�mm by 45�mm to use as a wall
stud.

Notice that the length (2400�mm in this case) is part of a system of
dimensional coordination based on a 600�mm module. Other lengths that are
available are 1200�mm, 1800�mm, 3000�mm, 3600�mm and so on.

Na�ve people with little experience in building still try to refer to a
90�mm by 45�mm timber as a 4 by 2 � they are quite unaware that the 4 by 2
never actually existed in that size as that always was just a nominal size.

All houses her are designed and built using millimetres. The area of the
house is then calculated using square metres, and then many sales staff dumb
this down to 'squares' of 100 square feet � but square feet are never
mentioned. The nett result is that the public is profoundly confused.
