I found 3000# green.

Water doesn't get heavier when it's frozen.

Do the mills use that figure to benefit you?

Now that is funny!! Mills don't do anything to benefit anyone but themselves. That is why it is all done by weight. Anyone can twist conversion numbers around but a ton is a ton.
Also, if you used 3000 pounds as a conversion number, that would be 20 cord on a 30 ton load. 20 cord would be pretty tough to fit on a truck unless you were in Michigan :D

The common conversion here is 4500lbs/cord but nearly everything is sold by weight.  Like it much more that way.  No arguing with the weigh scales.

Snowstorm, they have the same conversion number for both spruce and balsam fir? There is a lot of weight difference between those species.

here sp and fir is lumped together. fir will weigh more than sp most of the time. back in the 4ft days some mills would let you choose stick scale or weigh. if it was all fir sometimes you would gain by weigh. now you are not supposed to convert it . its to be by the ton. i remember hauling into the st regis mill about 30yrs ago and had several of there new foresters pilling 4ft wood in a rack just 4'x8' then weighting it one stick at a time

Doesn't all timber get lighter when frozen due to the sap being down?

I was asking because fir is significantly heavier than spruce  in my experience. I'm not sure what conversion numbers are used  at UPM Blandin, but I think it's seperate for spruce and fir. They stick scaled up until  a year and a half ago.

Our spruce is sold stick scale, but the conversion is 2.3 or 2.4 tons/cord.    Fir is heavier.   Some of the heaviest loads we produce are winter cut balsam fir.

Right, balsam is almost as heavy as red pine sometimes. That conversion factor seems to heavy for spruce, is that for balsam?
