When doing your figuring keep in mind that if your buying random length your cordage estimates are going to vary somewhat. So if your looking at that load someone drove into the yard and there are sticks of all lengths on the truck, just know that cordage estimation is going to be just as variable. We only based our estimates at the marketing board on 4 and 8 foot wood. And you could actually have 85 ft3
up to 100 ft3
in wood volume because of different diameters. If you look at the green weights of woods, we chose 100 ft3
(cunit) as the standard which meant we had 5500 lbs of wood in a cord of hardwood (maple, beech, yellow birch). Oak is a lot heavier when green, but since we have so little of it up here, we didn't bother factoring it in. As a rough estimate, several folks use 2 cords per thousand as a rule of thumb across all species. The logging contractors used this to pay cutters and landowners. Up here, loggers don't know what a m3
is, and even suggesting MBFM is way over the top. Cords is what they've always cut and there's no changing it.
Good luck with your figures.
