What is a Board Foot?
A **board foot** is the standard measurement for lumber volume in the United States. It’s equivalent to a piece of wood 1 foot long, 1 foot wide, and 1 inch thick. It’s not a direct measurement of physical size, but a calculation of total material.
Why Cubic Feet?
**Cubic feet** is a more universal measurement of volume. It represents the actual physical space the lumber occupies. You can convert board feet to cubic feet by dividing the board feet value by 12. This is useful for comparing lumber volume to other materials.
How is Wood Weight Estimated?
Wood weight is calculated by multiplying the **total cubic feet** by the average **density** of the selected wood type. Densities are provided in pounds per cubic foot ($lbs/ft^3$) and are based on averages for dried wood. The actual weight can vary based on moisture content and specific species.
