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 yards

The cubic yard (yd³) = 27 ft³ = 0.764554857984 m³ (exact). Standard unit for bulk wood by-products in North America: landscaping bark mulch ~$25-70/yd³, wood chips for biomass boilers, timber crib-wall volumes. Typical residential mulch job: 5-15 yd³. Arborist chips ≈ 180-200 lb/yd³ fresh. 1 yd³ = 27 ft³ = 0.7646 m³ ≈ 324 bf.
