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.
About Cubic metres
The cubic metre (m³) is the SI unit for all international timber trade and FAO forest statistics. Global roundwood production > 4 billion m³/year (2022); sawnwood ≈ 500 million m³/year. European C24 structural timber priced in EUR/m³; CLT mass-timber buildings use 500-2,000 m³ of panels. FSC/PEFC chain-of-custody tracks certified fibre in m³. 1 m³ = 1 stere = 35.315 ft³ ≈ 423.8 bf.
