About Hoppus tons
The Hoppus ton (H ton) = 50 Hoppus feet = 50 × (Ο€/4) ft³ ≈ 1.112 m³. The '50' approximated one ton of tropical hardwood by weight (teak/mahogany at 700-900 kg/m³ × 1.112 m³ ≈ 0.9 metric ton). Standard for British colonial timber imports - teak from Burma, iroko from West Africa, meranti from SE Asia. Superseded by m³ after metrication. 1 H ton = 50 H ft ≈ 1.112 m³.
