How to convert thousand board feet to cubic feet
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 MBF, b for the intermediate value in m³, and y for the result in ft³.
ft³ = MBF × 2.359737216 ÷ 0.028316846592000004
Worked examples
10 MBF ≈ 833.333333333 ft³
Step 1: (10 × 2.359737216) ≈ 23.59737216 m³.
Step 2: 23.59737216 ÷ 0.028316846592 ≈ 833.333333333 ft³.20 MBF ≈ 1666.66666667 ft³
Step 1: (20 × 2.359737216) ≈ 47.19474432 m³.
Step 2: 47.19474432 ÷ 0.028316846592 ≈ 1666.66666667 ft³.
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.
