How to convert cubic feet to cubic meters
A board foot is 1 square foot by 1 inch thick. Use actual dimensions for physical volume. Nominal lumber sizes, stacked cords, pallets, and ties need dimensions or packing assumptions and are excluded.
Use x for the value in ft³, b for the intermediate value in m³, and y for the result in m³.
m³ = ft³ × 0.028316846592000004
Worked examples
10 ft³ ≈ 0.28316846592 m³
Step 1: (10 × 0.028316846592) ≈ 0.28316846592 m³.
Step 2: 0.28316846592 ÷ 1 ≈ 0.28316846592 m³.20 ft³ ≈ 0.56633693184 m³
Step 1: (20 × 0.028316846592) ≈ 0.56633693184 m³.
Step 2: 0.56633693184 ÷ 1 ≈ 0.56633693184 m³.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Cubic feet
Cubic feet (ft³) measures volume lumber under the conventions above. The base value in m³ is (x × 0.028316846592), where x is the numerical value in ft³. Factors shown here are rounded for display; calculations use the stored factor.
About Cubic meters
Cubic meters (m³) measures volume lumber under the conventions above. The base value in m³ is (x × 1), where x is the numerical value in m³. Factors shown here are rounded for display; calculations use the stored factor.
