Board Feet Formula:
| From: | To: |
The square footage to board feet conversion calculates the volume of lumber in board feet based on the area in square feet and the thickness of the material in inches. This is commonly used in woodworking and construction industries.
The calculator uses the board feet formula:
Where:
Explanation: The formula converts square footage to board feet by accounting for the thickness of the material, with the division by 12 converting inches to feet.
Details: Accurate board feet calculation is essential for lumber pricing, material estimation, project planning, and cost control in woodworking and construction projects.
Tips: Enter square footage in sq ft and thickness in inches. All values must be valid (square footage > 0, thickness > 0).
Q1: What exactly is a board foot?
A: A board foot is a unit of volume for lumber equal to 144 cubic inches (12 in × 12 in × 1 in).
Q2: Why divide thickness by 12 in the formula?
A: Since 1 board foot equals 1 square foot at 1 inch thickness, we divide by 12 to convert the thickness measurement from inches to feet.
Q3: Can I use this for different wood species?
A: Yes, the formula works for any wood species as it calculates volume, though pricing may vary by wood type.
Q4: How accurate is this calculation for rough lumber?
A: This calculates nominal dimensions. For rough lumber, you may need to account for actual dimensions after planing.
Q5: Does this work for metric measurements?
A: No, this formula is specifically for imperial measurements. For metric, you would calculate cubic meters instead.
