Converting among Log Scaling Methods
Efficiently converting measurements among various log scaling systems, such as Scribner, Doyle, International 1/4 inch, and Cubic Volume, has been a critical challenge for forestry and timber industry professionals.
Recognizing the need for a seamless and reliable solution, the
The board foot log scale uses simple assumptions about how much of a log volume is recoverable. The relationships among these different scaling systems vary systematically with log diameter, as well as length, taper, defects, and measurement and utilization conventions.
A transition to cubic would improve the log market transparency by reducing the worst inequities of board foot scales and making regional comparisons easier. Calculated relationships between board foot and cubic scales can be derived from values found in scaling handbooks .
