    Tossing a few evergreen trees (Dale, spruce etc) from around the farmyard that would be 30+ years
    A guy going to buy for firewood was asking how many ton.
    What’s a good way to work this out

    Spruce has a density of about 400-700(kg/m3), i.e. it has about half the density of water, but will be denser when wet and freshly cut. Working out the m3 gives you the approximate tonnage.

    I've not heard of Dale.

    Cut firewood is normally sold by volume traditionally a cord (3.62 cubic meters). The volume remains constant while the weight can vary.

    A tree 2 ft diameter & 30ft high would be 2.5m3 @ 600kg/m3 would be 1.5ton

    So you’re saying soak all the wood beforehand you weigh it ;)

    After a morning like this they wouldn’t need any soaking
