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.
About Hoppus feet
The Hoppus foot (H ft) is a British-Commonwealth round-log unit devised by Edward Hoppus (1736): V(H ft) = (girth/4 in)² × length/ft, yielding Ο€/4 of the true cylindrical volume ≈ 78.54% - the usable square-sawn fraction. Replaced by m³ in UK trade (1963) but still used in Sri Lanka, Malaysia, Myanmar, and Bangladesh. 1 H ft = Ο€/4 ft³ ≈ 0.02224 m³.
