Board Feet Formula:
From: | To: |
The board feet calculation estimates the volume of lumber in a log using a simplified rule. It provides a standardized measurement used in the forestry and lumber industry to quantify wood volume.
The calculator uses the board feet formula:
Where:
Explanation: The formula calculates board feet by squaring the diameter, multiplying by the length, and dividing by 16. This simplified rule provides a quick estimate of usable lumber in a log.
Details: Accurate board feet calculation is crucial for timber pricing, inventory management, and determining the value of lumber. It provides a standardized unit for buying and selling wood products.
Tips: Enter the diameter in inches and length in feet. Both values must be positive numbers. The calculator will provide the estimated board feet measurement.
Q1: What is a board foot?
A: A board foot is a unit of measurement for lumber equal to 144 cubic inches (12" × 12" × 1").
Q2: Why divide by 16 in the formula?
A: The division by 16 is part of the simplified rule that accounts for saw kerf, slab loss, and other milling waste.
Q3: How accurate is this calculation?
A: This is a simplified estimation. Actual board foot yield may vary based on log quality, milling techniques, and species characteristics.
Q4: Should I measure diameter at the small end or large end?
A: For this calculation, use the average diameter or the small end diameter inside bark, depending on your local industry standards.
Q5: Can this formula be used for all wood species?
A: While the formula works for general estimation, different species may have varying recovery rates due to density and milling characteristics.
