Board Foot Formula:
From: | To: |
A board foot is a unit of measurement for the volume of lumber in the United States and Canada. It represents one square foot of lumber that is one inch thick, or the equivalent volume in different dimensions.
The calculator uses the board foot formula:
Where:
Explanation: The formula calculates the volume of lumber by multiplying the three dimensions and dividing by 12 to convert to board feet.
Details: Board foot calculations are essential in the lumber industry for pricing, inventory management, and project planning. It provides a standardized way to measure and compare different sizes of lumber.
Tips: Enter thickness and width in inches, length in feet. All values must be valid (greater than 0). The calculator will compute the board footage.
Q1: Why is board foot measurement used?
A: It provides a consistent way to measure and price lumber regardless of the specific dimensions of each piece.
Q2: How does thickness affect board feet?
A: Thicker boards contain more board feet per linear foot. For example, a 2-inch thick board has twice the board feet of a 1-inch thick board of the same length and width.
Q3: Are there standard lumber sizes?
A: Yes, but nominal sizes (like 2x4) are different from actual dimensions due to drying and planing. Always use actual measurements for accurate calculations.
Q4: How do you calculate board feet for multiple pieces?
A: Calculate board feet for one piece and multiply by the number of identical pieces, or enter the total linear feet in the length field.
Q5: What about metric measurements?
A: Board feet is an imperial unit. For metric, cubic meters are typically used instead.
