Does it mean 1.98m3 per tonne for the pine?

(and the others pro rata)

[slasherscot]

no . pine weighs 1 cubic metre to 1 metric tonne approx.......typo

[Quickthorn]

hope this some use as there is a lot of different ideas people have about weight and m3 it from foresters companion book my bible oldschool:001_smile:

 

softwood green weight cubicmeter weight conversion

pine=m3=1.98 tonnes

 

larch=m3=1.20 tonnes

 

dougfir=m3=1.15tonnes

 

spruce=m3=1.04tonnes

 

Hardwood green weight cubicmeter conversion

Beech=m3=0.97 tonnes

 

Ash=m3=1.28 tonnes

 

oak=m3=0.94 tonnes

 

 

I've looked at my copy of Forest mensuration from the FC. Except for pine, the figures are right if you mean cubic m per tonne..so 1.2 cubic m fresh larch (jap or hybrid) would weight 1 tonne. For pine, it's 0.98 cubic m per tonne, not 1.98.

:confused1: Does this mean that the figures above for example Larch is:1.20 tons per m3 or 1.20 cubic meter is 1 ton?

 

All the original figures equate to the amount of cubes per ton?

 

1.15 m3= 1ton (doug fir) ?

 

Hope I made sense?

[b101uk]

1 tonne (Metric) = 1000kg

1 ton (short or US) = ~907kg

1 ton (long or English) = ~1016kg

 

if the book is from the USA then it will be short ton, if from the UK pre Metric then it could be long ton unless spelt tonne or "metric ton"

thank you everybody for pointing out my mistake with the pine and making more sence out of it

[Ben Ballard]

also i jotted down when borrowed the book,spruce and douglas fir 2 month after felling april-september time would have 7% weight loss and pine 5% weight loss october-march would be 1.5% for spruce,douglas. and pines 1% ,2 month after felling,you can see wye foresters dont want wood sitting around for long time if selling it by the tonne

[Mesterh]

I'm more confussed now than I was before I knew anything:confused1:

[Justme]

I can see why the truckers need to charge by the ton for carriage but the wood should be sold by volume at all points in the chain.
