1. What is a Linear Feet to Board Feet Calculator?

Definition: This calculator converts linear measurements of lumber to board feet, the standard measurement for wood volume.

Purpose: It helps woodworkers, carpenters, and DIYers accurately estimate wood quantities for projects and purchasing.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ BF = \frac{Linear\ Feet \times T \times W}{12} \]

Where:

Explanation: The formula accounts for all three dimensions of the wood to calculate its total volume in board feet.

3. Importance of Board Feet Calculation

Details: Board feet is the standard measurement for lumber pricing and inventory. Accurate conversion ensures proper material estimation and cost control.

4. Using the Calculator

Tips: Enter the length in feet, thickness in inches, and width in inches. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What exactly is a board foot?
A: One board foot equals 144 cubic inches of wood (12" × 12" × 1").

Q2: Why divide by 12 in the formula?
A: The division converts the cubic inches result to board feet (since 1 board foot = 144 cubic inches, and 12" × 12" = 144).

Q3: How do I measure thickness and width?
A: Measure in inches at the thickest/widest point for rough lumber, or actual dimensions for dressed lumber.

Q4: Does this work for metric measurements?
A: No, this calculator uses imperial units. Convert metric to feet/inches first.

Q5: How does this differ from square feet?
A: Board feet measures volume (including thickness), while square feet only measures surface area.
