Log Volume Calculator
Result
Step-by-step calculation
Formula
Volume (m³) = π/4 × d² × L (Huber, d = mid-diameter in m, L = length in m)
Girth = π × d; Hoppus volume = (Girth ÷ 4)² × L
Cubic feet = m³ × 35.3147Worked example
Calculated with the default values shown in the form.
Technical notes
- Measure the diameter at the middle of the log, under bark, and average two perpendicular readings.
- Hoppus volume deliberately under-states true volume (about 78.5% of it); use Huber for yield calculations.
- Buying rules differ by region. Confirm the measuring rule in your purchase contract.
