Can anyone tell me how to convert cubic meters or feet into linear meters or feet. I am going nuts trying to get it. Why can't timber merchants use plain language so we can all understand it?? :evil:

You need to know how wide and thick your stock is before you can convert it into linear measurements - and that's why they use it, because it is universal across all different timber sizes.
There are 144 linear feet of 1" x 1" in a cubic foot (imagine building a stack of 12" long lengths of 1" x 1"- to get that stack to be a cubic foot, you'd need 12 lengths in each layer to make it 12" wide, and 12 layers to make it 12" high), but only 8 linear feet of 6" x 3" (two 1 foot lengths per layer, 4 layers).

Naturally different
volume = length x cross section (bxh)
so
length = volume/cross section
1 cu ft (12 x 12 x 12) as 6 x 1 = 1/(0.5 x 0.833) = 24 linear ft
easier in inches (1 cu ft = 1728 cu in)
1 cu ft as 6 x 1 = 1728/(6 x 1) = 288 in = 24 linear ft
Hope this helps?

Hi Mailee
If you use google it has a great feature (calc). In the search box if you put for example:
12 inches x 13 feet x 1.5 inches in cubic feet
and hit enter
the result is shown!
You can also mix measures for example:
300mm x 2400mm x 25mm in cubic feet
or
3.5 inches x 300mm x 1 yard in cubic metres
etc etc
try it and see
(It also does weights and temperatures (be careful about imperial and american measures though) and lots of other stuff)

Aw thanks guys, I knew you would be able to help me. Oh and yes Philly, I am the lazy type.

I know exactly what you mean Mailee, it does your head in!
My solution is this;
I buy mainly 1" timber. It normally comes in 8' lengths. On average it is about 6" wide.
Therefore each plank is approx one third of a cubic foot - work it out!
If you keep this in mind when buying timber it makes life much easier. For instance, if American Oak is £25.50 per cubic ft +VAT that works out at £30 per cubic ft. So an average plank costs you a tenner!
In the back of my mind I always have these prices currently;
Oak
Sapele
Ash
Beech £10 per plank
Maple
Walnut
Cherry £15 per plank
It's very rough and very approximate, but it works!
Cheers

Thanks for that Dan, I shall bear that in mind. I can't understand it either if I had wanted to be a mathematician I would have taken a different interest but I am more interested in creating things in wood. :roll:
