>The thought just occured to me that since our neighbors to the north are using the metric system of measurements, what unit do they use to buy and sell lumber? I thought maybe board meter? Any how, maybe someone familiar with the trade in Canada could enlighten an old country boy. If anybody is familiar with Australia's system, I'd like to know that too. In closing let me congradulate our cousins across the border for making the change. I use metric often in the shop and find it a whole lot easier that feet, inches, 16ths etc.

>Ya know, it's funny but the construction industry hasn't really gone metric. Our 2x4's are just like yours and our sheet goods are in 4' x 8' sheets. The exception to this is in plywood thickness. Our 1/2" is actually in some millimetre measurement. I believe our lumber suppliers buy their stock by the board foot, at least the non-construction stuff like maple, oak, exotics etc.

P.S. Happy Thanksgiving to all of my northern brethren!

It's called "cubic meter" or "m3"

>Though, nobody in Canada deals with it as far as lumber goes. All imperial system is still in the works.

Chico...

1 cubic meter = 423.776 bdft.

>The Canadian system is either both systems of parts of both system so it's pretty confusing. In addition to all that, I use some Japanese tools. I guess it keeps the mind young.

I used to do wood in the metric system, but I have converted to the Imperial system, under various influences, like the US, the prevalent boat plans, and house construction system. I don't actually find metric any easier to use. It's easier to halve a dimension by doubling the denominator on the fractional component, though either way is easy enough. I would certainly prefer to do science in the metric system but everyday life is pretty much a wash.

In an effort to create harmony, I now refer to metric as Client State measures. In an Imperial system France fits in as a client state. Metric sounds so Bauhaus, which really isn't fair to the French.

In Aus, officially it's cubic metres, but

>apart from the wholesale level, almost no one uses it

a cubic metre of Aussie hardwood weighs in close to a ton � rather a lot of timber

mostly timber is sold by width and thickness in increments of 300mm. The old imperial sizes (12x2, 4x1, 6x1�, etc) have been converted to the equivalent metric sizes (300x50, 100x25, 150x38, etc).

as far as I know, we've never used the 1/4 sizes used in the US

>This is where it really gets interesting. As a baker/cook by trade, I insist on using metric, makes things a whole lot easier for costing,inventory calculations, and especially recipie conversions, but most of this is done with metric weights, not measurement.

When working with wood, I still find it much easier to use imperial. Virtually all the lumber here (at least in B.C.) is still in imperial, hardwood sold by the board foot, or, if dimensioned, by linear foot, and since most of my projects are made for our house that was made with imperial measurements (8'ceilings, studs on 16" centers, etc.), I am reluctant to go to metric. Now, that being said, it drives me absolutely nuts to work with fractions, won't use a rule that has anything smaller than 1/16" graduations, too confusing. So with measurements smaller than an 1/2" I'll cheat and use millimeters, far simpler.

The French and metric? Think it was Napolean who got the whole metric thingee rolling. Seems his quarter-masters were getting hosed on buying supplies for the army, one city/town/region used one system, the next another. Napleon put out a commision for a universal system, and a group of scientists and philosophers developed a system based on the largest common denominator in the world, water. (Napolean also put out a commision for preserving food, crafty old guy knew an army marches on it's stomache. It was Appert who preserved fresh dairy cream, got the commision, and paved the way for canning other foods) Metric system was "adopted" immediately, those who didn't "adopt" it got to check out first hand how good the edge on the guillotine was...

>Hi Ian,

Trust that all is well.

The sizes I buy in Tassie Oak (cut locally) are 3/4" rough, 1" rough, 1.25" rough, 1.5" rough, 1.75" rough and 2" rough. Above 2", things jump upwards by an inch at a time. These translate to 12mm, 19mm, 25mm, 32mm, 38mm and 45mm dressed.

The most commonly used sizes are 12mm, 19mm, 32mm, 38mm

Cheers,

Andrew

I hope the CDs turned up OK

I can also get a video on timber bridge maintenance if you're interested

cheers
