How the Log Volume Calculator Works

Built to FAO/UNECE international standards with Ο€/40000 precision (cm β†’ mΒ³).

  • Smalian: V = L/2 Γ— (A₁ + Aβ‚‚) – best for tapered logs
  • Huber: V = L Γ— A_mid – fastest field method
  • Newton: V = L/6 Γ— (A₁ + 4A_mid + Aβ‚‚) – Β±1% accuracy

Log Volume Calculator: Global Units & Conversions

  • 1 mΒ³ = 35.315 CFT = 0.2759 Hoppus ton
  • 1 CFT = 0.0283 mΒ³
  • 1 Hoppus ton = 50 CFT (imperial)
