1. What is Board Foot Calculation?

The board foot is a unit of measurement for the volume of lumber. For log siding, the calculation includes a siding factor to account for the unique characteristics of siding production.

2. How Does the Calculator Work?

The calculator uses the board foot formula for log siding:

Where:

• \( BF \) — Board feet
• \( T \) — Thickness in inches
• \( W \) — Width in inches
• \( L \) — Length in feet
• \( S \) — Siding factor (dimensionless)

Explanation: The standard board foot calculation is adjusted by a siding factor that accounts for the specific characteristics of log siding production.

3. Importance of Board Foot Calculation

Details: Accurate board foot calculation is essential for lumber pricing, inventory management, and project planning in woodworking and construction.

4. Using the Calculator

Tips: Enter thickness and width in inches, length in feet, and the appropriate siding factor. Typical siding factors range from 1.0 to 1.5 depending on the siding profile.

5. Frequently Asked Questions (FAQ)

Q1: What is a standard siding factor?
A: Standard siding factors typically range from 1.0 to 1.5, with 1.0 being for plain boards and higher values for more complex profiles.

Q2: How does board foot differ from square foot?
A: Board foot measures volume (thickness × width × length), while square foot measures only surface area (width × length).

Q3: Why divide by 12 in the formula?
A: The division by 12 converts the width from inches to feet to match the length unit, making the result in cubic feet.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise, but actual lumber volume may vary slightly due to milling processes.

Q5: Can this be used for other lumber types?
A: Yes, by setting the siding factor to 1.0, this calculator works for standard lumber board foot calculations.
