Board Foot Formula:
Where:
BF = Board feet
V = Volume in cubic inches
| From: | To: |
A board foot is a unit of measurement for the volume of lumber. One board foot equals 144 cubic inches (12" × 12" × 1"). It's commonly used in forestry and woodworking to quantify wood volume.
The calculator uses the board foot formula:
Where:
Explanation: The formula converts cubic inches to board feet by dividing by 144 (since 1 board foot = 144 cubic inches).
Details: Accurate board foot calculation is essential for estimating lumber volume, pricing wood products, and planning tree planting projects.
Tips: Enter the volume in cubic inches. The value must be greater than 0. The calculator will automatically compute the board feet.
Q1: How do I measure volume in cubic inches?
A: For a rectangular piece: length × width × thickness (all in inches). For logs: use specific log volume formulas.
Q2: What's the difference between board feet and linear feet?
A: Board feet measures volume (including thickness), while linear feet only measures length.
Q3: How many board feet are in a 2x4?
A: A 2x4 that's 8 feet long contains 5.33 board feet (1.5" × 3.5" × 96")/144.
Q4: Why is board foot measurement important for tree planting?
A: It helps estimate future lumber yield and economic potential of planted trees.
Q5: Are there standard board foot calculations for different tree species?
A: Yes, different species have different conversion factors based on their typical dimensions and growth patterns.
