converting solid wood volumes

[MR TREEBUS]

I know its been on here before and i have spent 20 mins searching before anyone says can some one please provide link to conversion rates for solid cubic metre of timber to loose,cheers in advance

Looking to answer the same question, try this!

As a rough guide 1m3 of cord wood will yield around of 1.5m3 of split logs (loose or bagged, less if stacked).

 

It's quite a bit different if you talk weight to volume but that wasn't the question.

It also depends how tight you stack, bendy wood and size of logs within the cord? what would you say on weight to volume? my stacks are worked out on 50/50 air/wood and weighted at 1.5 tonne per cube.

Wood density for all but a few hardwoods (teak I think is one) is less than water. Hence wood tends to float on water. 1 metric ton of water is 1m3 so wood in all but the very rare exception is under 1000kg per cube. That is for solid wood, no gaps.

This may also be worth a look.

I take it Oak, being heavy will not even produce 1.5 loose M3 per ton?

(Just been looking at some nice stuff roadside)

I might be wrong but beech is heavier than oak and elm more than those?

Did not feel it on Tues when I was processing fresh cut lumps of oak, sycamore and beech. I would have said oak was the heavyist followed by Beech but it is difficult to be precise as the lumps were slightly different sizes.

The people I buy cord from offered me oak at a lower price as being a dense wood it splits to a smaller volume that you can't charge more for than white woods eg. sycamore or ash. Their words not mine. I prefer to avoid oak as a prime wood in a batch as it's hard to split if dry and takes an age to dry if green.

 

For anyone that wants to find out densities of species of woods there are U.S. research papers googlable that run down the enegy yield of woods. Seeing all woods yield the same energy weight for weight the higher energy yield relates directly to a higher density of wood and vice versa.

I have turned it down for that reason. I think its quite possible that it may only produce 1m3 loose firewood per ton which would make it tight as regards profit. That and the fact that a lot of it was on the biggish side and wouldnt go through the processor.
