1. What is Board Foot Measurement?

A board foot is a unit of measurement for the volume of lumber. One board foot equals 144 cubic inches (12" × 12" × 1"). This calculator estimates the board feet in a log based on its diameter and length.

2. How Does the Calculator Work?

The calculator uses the board foot formula:

Where:

• \( BF \) — Board feet
• \( D \) — Diameter of log in inches (small end)
• \( L \) — Length of log in feet

Explanation: The formula approximates the usable lumber that can be obtained from a log, accounting for the squaring of the log during milling.

3. Importance of Board Foot Calculation

Details: Accurate board foot calculation is essential for lumber pricing, inventory management, and project planning in woodworking and forestry.

4. Using the Calculator

Tips: Measure the diameter at the small end of the log in inches. Enter the length in feet. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 16 in the formula?
A: The divisor accounts for the conversion from round log to square lumber and standard board foot dimensions.

Q2: How accurate is this calculation?
A: It provides a rough estimate. Actual yield depends on sawing method, log taper, and defects.

Q3: Should I measure diameter at large or small end?
A: Standard practice is to measure the small end inside the bark.

Q4: Does this work for metric measurements?
A: No, this formula is designed for imperial units (inches and feet).

Q5: What's the difference between board feet and linear feet?
A: Board feet measures volume (thickness × width × length), while linear feet only measures length.
