Log board feet conversion into cord volume

[mifirewoodguy]

Does anyone know of a conversion method of figuring board feet in log form and converting it into cord wood volume? is there a method out there or is it just a guesstimate?

wouldn't the logs have to be uniform in size? a 12" diameter log 15 feet long, and most likely tapered, would yield different than a log 24" in diameter and 25 feet long.

the only way to calculate would be if everything was of a known and equal value....right?

I guess if you're going to all the trouble...

Weigh a few board feet of like wood and then you'll have your multiplier for the firewood. Of course, you would have to debark all your firewood, make sure it's dried the same, etc.

Never mind.

A cord of wood contains 80 cubic feet of solid wood.

A 14 inch round one foot long is very close to a cubic foot. so 80 feet of 14 inch rounds= one cord.....and a 2 foot round has 3.14 cubic feet, so about 27 feet of it will equal a cord.

With the way taper is accounted for in scaling timber, I reckon a 12 inch 40 foot log would about equal 1/2 cord, and that is 200 board feet, Scribner scale.

Also, when cut into lumber, depending on the size of the wood, and the way it is cut, there will be quite a gain in recovered board feet. A cubic foot of wood contains 12 board feet....of course the amount of loss will vary depending on whether a blade or band mill was used to cut the wood....but that digresses from the question.

General rule of thumb in the logging industry in New England is 500BF per cord of wood. That is using Internantional scale. No idea if you are using scribner or doyle.

Cord Volume

Divide your cord volume by 1.576 to get thousand board feet Scribner scale.
