About Cubic feet
The cubic foot (ft³) = 0.028316846592 m³ (exact) - the primary US lumber volume unit for large structural timber; also underlies the cord (128 ft³) and board foot (1 bf = 1/12 ft³ nominal). US Forest Service sale contracts specify cruise volumes in Mbf or ft³. Export docs for EU/Asia convert to m³: 1 m³ = 35.315 ft³. 1 ft³ = 0.02832 m³ = 1,728 in³ ≈ 12 bf.
About Cords
The cord is the standard North American firewood/pulpwood unit = 4 ft × 4 ft × 8 ft stacked = 128 ft³ = 3.6246 m³ (exact). NIST Handbook 44 requires all US firewood to be sold in cords or legal fractions. Seasoned split hardwood ≈ 20-24 million BTU/cord; air-dry pine ≈ 15-18 million BTU/cord. 'Face cord' or 'rick' is NOT a legal unit. 1 cord = 128 ft³ = 3.6246 m³ = 8 cord feet.
