Board Feet Formula:
From: | To: |
Board feet is a unit of measurement for lumber volume. One board foot equals 1 foot long × 1 foot wide × 1 inch thick (or equivalent volume). It's the standard unit for buying and selling hardwood lumber in North America.
The calculator uses the board feet formula:
Where:
Explanation: The formula calculates the volume of wood in board feet by multiplying the dimensions and dividing by 12 to convert to the standard board foot measurement.
Details: Accurate board feet calculation is essential for lumber pricing, project planning, material estimation, and cost control in woodworking and construction projects.
Tips: Enter linear feet in feet, width in inches, and thickness in inches. All values must be positive numbers. The calculator will provide the volume in board feet.
Q1: What's the difference between linear feet and board feet?
A: Linear feet measures length only, while board feet measures volume (length × width × thickness).
Q2: How do I convert board feet to linear feet?
A: You need to know the width and thickness. Linear Feet = (Board Feet × 12) ÷ (Width × Thickness).
Q3: Are there standard lumber dimensions?
A: Yes, nominal dimensions (like 2×4) are slightly larger than actual dimensions due to planing and drying.
Q4: Does this calculation work for all wood types?
A: Yes, the formula works for any wood type, though pricing may vary significantly between species.
Q5: How accurate is board feet measurement for estimating projects?
A: It's the industry standard, but always add 10-15% extra for waste, cutting errors, and defects.
