Example Calculations

Example 1

Board: 2″ × 6″ × 8′ | Board Feet = (8 × 6 × 2) ÷ 12 = 8 BF

Example 2

5 boards: 1.5″ × 4″ × 10′ | Per Board = (10 × 4 × 1.5) ÷ 12 = 5 BF | Total = 5 BF × 5 = 25 BF

Example 3 (Cost)

Price per BF = 3∣Totalcost=25×3=3 | Total cost = 25 × 3 = 3∣Totalcost=25×3=75

Board Foot Information

A board foot is a unit of measurement for lumber volume. One board foot equals 144 cubic inches or 1/12 cubic foot. It's calculated by multiplying thickness (inches) × width (inches) × length (feet) ÷ 12.

Calculation Formulas

Length in Feet

BF = (Length_ft × Width_in × Thickness_in) ÷ 12

Length in Inches

BF = (Thickness_in × Width_in × Length_in) ÷ 144

Key Conversions

1 Board Foot =144 cubic inches

1 Board Foot =1/12 cubic foot

Total BF =Number of pieces × BF per piece

Total Cost =Total BF × Price per BF

Example:A 2" × 6" × 8' board = (8 × 6 × 2) ÷ 12 = 8 board feet. For 10 pieces, total = 80 board feet.
