A tool exists that determines the approximate board foot volume of a log based on its diameter inside the bark at the small end and its length. This calculation uses a specific formula established to estimate lumber yield from logs, providing a standardized method for valuation and trade within the timber industry. The formula, known as the Doyle Log Scale, is (Diameter – 4)2 * Length / 16, where Diameter is measured in inches and Length in feet.
This method plays a vital role in the forest products sector, allowing for fair pricing and efficient resource management. Historically, it was one of the earliest attempts to quantify timber volume, facilitating commerce and providing a common language between loggers, millers, and landowners. While it tends to underestimate volume compared to other scales, particularly for smaller logs, its simplicity and widespread historical use have made it a significant part of timber assessment.
