Use this forestry calculation to summarize a measured tree, plot, canopy, fuel, biomass, carbon, growth, density, or wood-volume quantity under a stated inventory convention.

Merchantable Cubic Meters (m3)

Required number input.

Total Stem Cubic Meters (m3)

Required number input.

Merchantable stem volume as a percentage of total measured stem volume. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Merchantable Percent (percent)

The resulting merchantable percent returned as a number.

• Tree-volume estimates depend on diameter locations, length, bark convention, taper, form, defects, species, moisture, and merchantability rules. Huber, Smalian, Newton, and simple form-factor methods can differ for tapered or irregular logs.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Use locally validated equations and inventory protocols, retain species and measurement metadata, aggregate with appropriate plot expansion and sampling weights, and report uncertainty with stand-level results.

• Pulp Volume Percentage

  Pulpwood volume as a percentage of total merchantable volume.

• Sawlog Volume Percentage

  Sawlog volume as a percentage of total merchantable volume.

• Biomas Single Tree

  Dry aboveground tree biomass from measured stem volume, basic wood density and an explicit biomass expansion factor.
