Default Understanding Price Quote Of Timber Yard

Hi,
I've asked a timber merchant for their price on timber. They came back to me with £1096.00 per m3. I don't really understand terms like running metre or board feet etc.
How do I work out what six boards, 30cm wide x 5cm thick by 2.5m long would cost me?
Thanks.

length (2.5M) times width (1.8M) times thickness (.05M) = your cubic meter measure...

30x6 = 180CM or 1.8M total width of the 6 boards laid side by side....
1.8x2.5 = 4.5² or 4.5M square...
5CM thick is .05M...
.05x4.5 = .225M³...

£1096x.225 = £246.60

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

This has been a mystery to me. I think what Stick is saying is that you buy wood by the cubic inch (or cm). Is that correct? So a board foot would equal 12x12x1 inches, or 144 cubic inches? Is that correct?

Thinking of it as a "cubic" measure is any easy way to keep the math in mind. The tricky part is the thickness measure as a lot of vendors will round up 1/2 and 3/4 boards to 1 inch.

That is correct for a board foot. Some rough sawn boards are also still measured by quarters so a 10/4 board would be 2.5" thick. The metric system usually goes actual volume. A 3/4" thick board would be 19mm instead of 25.4(1").

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Another example of the Metric Monsters taking a simple concept and turning it into meaningless mush.
The 'Board Foot' does make sense, if you're buying large quantities of lumber. But for the hobbyist who wants a particular board, which has maybe a couple of fairly random edges and maybe a big knot at one end, the yard guy with the measuring stick is either his friend or his enemy...the hobbyist is at his mercy. If Y.G. says it's 3.7 B.F. that's what you're going to be paying for.

The concept of M3 is complete b.s., unless you're buying full lifts, or railcar loads.
For framing lumber, on the other hand, where each piece is the same size, the alternate price per running foot (or metre) makes more practical sense 20 pcs-12'/2x4 @ $.50/linft... 20x12x.5= price
Sure the yards' computers will have the B.F. price, but they also have the conversion factor.
I doubt that you could even fit a M3 into a small car! That's a lot of weight. You're always going to end up with a M3 volume of something to two decimal places (.05 M3 for example) if you're buying small amounts of lumber.
As I've argued before, metric has no connection to the Human experience. Trust the French...
