Board Foot Formula:
From: | To: |
Definition: This calculator estimates the board feet of lumber based on the thickness, width, and length of the wood.
Purpose: It helps woodworkers, carpenters, and DIYers determine how much lumber is needed for projects.
The calculator uses the formula:
Where:
Explanation: The formula calculates the volume of lumber in board feet, where 1 board foot equals 144 cubic inches (12" × 12" × 1").
Details: Proper board foot estimation ensures accurate material purchasing, cost estimation, and project planning.
Tips: Enter the thickness and width in inches, and length in feet. All values must be > 0.
Q1: What exactly is a board foot?
A: A board foot is a unit of measure for lumber equal to 1 foot long × 1 foot wide × 1 inch thick (or equivalent volume).
Q2: How do I calculate board feet for multiple pieces?
A: Calculate board feet for one piece and multiply by the number of identical pieces needed.
Q3: Does this work for metric measurements?
A: No, this calculator uses imperial units. For metric, convert to inches and feet first.
Q4: How accurate is this calculation?
A: It's mathematically precise, but actual lumber dimensions may vary slightly due to milling processes.
Q5: Should I include waste in my calculations?
A: The calculator doesn't account for waste. Add 10-20% extra depending on your project's complexity.
