Is there a simple method to estimate how many cords of split wood are in a downed tree or log? Also, which would contain more wood, a cord of split wood or a cord of rounds?
No the only way to know for sure is to split it and stack it into 4X4X8 foot piles. Maybe their's a formula. Dec 9, 25 Central Vermont. Split wood of which you speak is what, Apprentice?? OK, woodmaster gave me the idea to look for a log volume calculator but they calculate Doyle, Scribner or International units, which measure the amount of lumber that can be extracted from a log.
I wasn't able to make use of these directly but it got me thinking. A cord 4x4x8 contains cubic feet. Of course, wood doesn't stack perfectly so there is not cubic feet of solid wood in a cord.
After some Googling, it seems reasonable to assume about 85 cubic feet of solid wood per cord. Next, the volume of a cylinder is Pi x radius squared x length. A tree tapers as it grows so it is not a perfect cylinder; I am assuming a taper of. To calculate the volume of the log I calculate the volume twice -- once using the diameter at the large end, and once using the diameter at the small end and then take the average of the two.
I will test it the next time I cut and stack firewood. In any case, to get one cord of stacked wood, I calculate it would take a single log 31 feet long, with a diameter of 24 inches on one end and And there doesn't seem to much difference between split or rounds becasue if you took that 31 foot log and cut it into four foot sections it would pretty much stack into a 4x4x8 foot area.
The other is the modern version, using your smartphone or tablet. Select a tree to measure for height. Close one eye. Point your opposite hand at the tree, keeping your elbow rigid. Now make a fist and point your thumb upward and your little finger toward the ground. Spread your thumb and little finger as far apart as possible. Line up your open eye with the top of your extended arm. Holding this arm and eye in this position, walk either toward the tree or away from the tree until the top of your thumb lines up with the top of the tree and the bottom of your little finger lines up with the base of the tree.
Mark the spot you are standing. Measure from the spot you were standing to the base of the tree. If you know the length of your stride, you can count your steps to the tree.
Then just multiply the number of steps times the length of your stride to get the distance to the tree. We like the free EasyMeasure app. It is available for Android or IOS. EasyMeasure uses the camera feature of your smartphone or tablet to measure height of a tree using the height of the camera from the ground and the tilt of the phone. Before using, you have to set the app so it knows the height from the ground at which you typically hold the smartphone when taking photos generally, eye-level is your height minus 4 inches.

You should count on around 6 cords for a properly packed single grapple load. Tough to tell from a couple of pictures but that load does not look to be well packed on the truck and has several bent logs that create air space on the load.
The grapple also takes up a lot of space on top of the load. There are also several logs that look like they are punky in the middle. If I had to make a best guess based on what it looks like on the ground I would say you have around 5 to 5.
Please post actual amount when you cut split and measure. Good luck! This spring I dropped a 22" shagbark hickory that I computed was about 48' tall with 14' of straight trunk. I didn't see the wood on the truck , just a pile of logs when I got home from work.
I now wish I'd bought 10 loads then as they only did that for that one year at that price. When I figured the volume for the 12" round it should have been about I gave the volume for a 24" round 20' long at 63 cubic feet. At any rate the guys are right that a cord of wood is cubic feet tightly stacked, so with the airspace you would get always get more wood no matter how tightly you stacked it.
I just figured this way if you needed a minimum amount you wouldn't "cut yourself short" It's just a rough idea anyway, trees don't often grow perfectly round and the same diameter from ground to top.

However, it is true that a cord the way it's written takes into effect airspace in a tightly stacked pile of wood. BlackCatBone said:.
You can think of it this way for a quick estimate. If your log could be a perfect 8" diameter end to end. Make a row of 6 logs side by side and your row is 4 feet wide. Stack 6 of those rows on top of each other to get 4 feet high. So if they are 8' long you have a cord. Obviously after cutting and splitting it will stack up differently.
