The base dimension of the module is 100 mm. That means any factor of 100 mm is permitted. 600 mm is permitted as it is afactor of 100, 6 times. A 600 mm module will only have factors of 600, 1200, 1800, 2400, etc.
Even if someone stuck to these sizes, they would still be following the 100 mm module. ----- Original Message ----- From: "Pat Naughtin" <[EMAIL PROTECTED]> To: "U.S. Metric Association" <[EMAIL PROTECTED]> Sent: Monday, 2003-10-27 14:59 Subject: [USMA:27322] Re: Lumber in the U K Dear Euric and All, on 2003-10-27 09.50, Mighty Chimp at [EMAIL PROTECTED] wrote: <snip> >> Notice that the length (2400 mm in this case) is part of a system of >> dimensional coordination based on a 600 mm module.

In Australia at the time of metric conversion, a very serious attempt was made in the building industry to introduce a 600 mm module. 600 mm was a preferred module to 300 mm, and this in turn was preferred to a 100 mm module. These preferences (set in the early 1970s) still profoundly influence the sizes of many, if not most, of our building components, thus saving millions of dollars each year for the Australian building industry.
