Board Foot Formula:
| From: | To: |
Board foot is a unit of measurement for lumber volume. It represents a piece of wood that is 1 foot long, 1 foot wide, and 1 inch thick (or its equivalent). The calculation accounts for nominal dimensions and adjustment factors for actual yield.
The calculator uses the board foot formula:
Where:
Explanation: The formula calculates the volume of lumber in board feet, accounting for standard dimensions and any necessary adjustments for waste or other factors.
Details: Accurate board foot calculation is essential for lumber pricing, inventory management, project planning, and material estimation in woodworking and construction projects.
Tips: Enter nominal thickness and width in inches, nominal length in feet, and adjustment factor. All values must be positive numbers. The adjustment factor is typically 1.0 for standard calculations but can be adjusted for specific yield requirements.
Q1: What are nominal dimensions vs actual dimensions?
A: Nominal dimensions refer to the size designation of lumber before planing and drying (e.g., 2x4), while actual dimensions are the smaller measurements after processing.
Q2: When should I use an adjustment factor other than 1.0?
A: Use adjustment factors for waste allowance, moisture content, or specific yield requirements in specialized applications.
Q3: How does board foot differ from other lumber measurements?
A: Board foot measures volume, while linear foot measures length and square foot measures area. Board foot is the standard for lumber pricing.
Q4: Are there standard board foot calculations for different wood types?
A: The calculation method is standard, but different wood types may have different density and yield characteristics that could affect the adjustment factor.
Q5: Can this calculator be used for metric measurements?
A: This calculator uses imperial units. For metric measurements, convert to appropriate units or use a dedicated metric calculator.
