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 Steres
The stere (st) = exactly 1 m³ - a metric firewood unit from the 1793 French Republican system. Still used colloquially in France, Germany, and Switzerland: Ster/Raummeter (stacked m³), Festmeter (solid m³ = fm), SchΓΌttraummeter (loose chips ≈ 0.4 fm). One stacked stere contains ≈ 0.5-0.7 m³ of actual solid wood. 1 stere = 1 m³ = 35.315 ft³ ≈ 424 bf.
