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.

Dry Biomass Kilograms (kg)

Required number input.

Carbon Fraction

Required number input.

Tree carbon mass from dry biomass and user-supplied carbon mass fraction. 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]

Carbon Kilograms (kg)

The resulting carbon kilograms 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.

• Co 2 Equivalent Single Tree

  Carbon-dioxide equivalent mass from tree carbon mass using molecular mass ratio 44/12.

• Basal Area Single Tree

  Tree stem cross-sectional basal area at breast height in square metres from DBH in centimetres.
