Cubic meter of roundwood to tonnes estimate needed

[Woodworks]

I know it's been discussed before but cant find a clear answer. Been offered some nice beech thinnings but they are being sold by per m3 and I have only bought by the tonne before. All freshly cut but very tidy. What is the likely ratio?

Should help,

Thanks but I might question that table. Pine weighing 1.98 tonnes

 

Thought fresh beech was about as heavy as you can get with native species.

De ja vu. Green softwoods are the wrong way round. Larch is circa 0.85t per m3 FF. 0.97t for beech sounds about right.

Presuming that is for solid wood but how much do I allow for air gaps with clean roundwood stack?

In general 0.55 for hardwood, 0.7 for softwood. Nice plantation beech would be more like 0.65 tho...

So if they are asking 40 a cube I would be paying around a £60 per tonne?
