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.

Total Aboveground Kilograms (kg)

Required number input.

Stem Kilograms (kg)

Required number input.

Ratio of measured total aboveground dry biomass to inventoried stem dry biomass. 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]

Expansion Factor

The resulting expansion factor returned as a number.

• Biomass and carbon estimates depend on species-specific allometry, diameter range, height, wood density, expansion factors, below-ground allocation, carbon fraction, mortality, decay, and plot sampling. CO₂ equivalent is not the same as verified sequestration credit.
• 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.

• Biomas Single Tree

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

• Form Factor

  Tree stem form factor: measured stem volume divided by basal area times tree height.

• Fuel Load Total

  Total areal fuel load from measured live and dead dry-mass loads in kg/m².
