What this calculator does
This tool estimates the weight of a round log by treating it as a cylinder and multiplying its volume by the average density of the wood species while still green (freshly cut, with high moisture content).
The formula
Volume = π × radius² × length (a cylinder). Weight = volume × density. Green wood density varies significantly by species and moisture content, so the values used here are typical averages, not exact figures.
Real log weight can vary widely due to moisture, taper, knots, and bark. Use this as a planning estimate for handling and transport, not an exact measurement.
