Do you know how to estimate cordwood from stem diameter and length? I'm looking for a formula or table to calculate the cordwood of casualty trees.

I have used the following from the Forester's Field Handbook, published by the U.S. Forest Service on cooperation with CO, KA, NE, SD, WY. Publication # 1-31-4-79. The copy I have was printed in 1979.

Softwood, less than six inches diameter, divide the cubic foot volume by 90. Softwood, six inch to twqelve inch, divide the cubic foot volume by 95. Hardwood, less than six inch, divide the cubic foot volume by 85. Between six and twelve inch, divide the cubic foot volume by 91. This is for straight and smooth bolts, let me know if bolts are rough and/or crooked, slightly different numbers. Another method is, fi you can calculate the number of board feet, divide by 500 to determine a standard cord (4x4x8 feet)

In addition to what Bill posted, I think there is a formula for cubic volume (cu.ft. or bd.ft.?) that assumes a typical taper over length from butt or lets you plug in taper. I'd look in a forestry text book.

There are also log scaling rulers that reflect such formulas. There are different types with different inherent formulas and different results. One is the Scribner rule.
