About Board feet
The board foot (bf) is the standard lumber-trade unit in the USA, Canada, and the Philippines: 1 ft × 1 ft × 1 in = 144 in³ = 0.002359737216 m³ (exact). Always calculated from nominal dimensions - a 1×6×8 ft board = 4 bf nominal, actual dressed volume is less. Hardwood lumber priced from ~$2/bf (common poplar) to $100+/bf (premium walnut). Log rules: Doyle (SE USA), Scribner (Pacific NW), International ΒΌ-inch (most accurate). 1 bf = 144 in³ = 0.00236 m³ ≈ 1/12 ft³.
