Forestry & Timber Calculators
Convert tree breast height diameters to basal area metrics, assess merchantable standing lumber volumes, calculate dry carbon dioxide sequestration offsets, analyze canopy light transmissions, and scale stacked cords of firewood.
Carbon Sequestration
Determine the total green weight, dry weight, stored carbon, and lifetime CO2 equivalent sequestered by a tree based on species and size.
Species & Biomass Inputs
Forestry Core Report
Dendrometric / SilviculturalLifetime CO₂ Sequestered (CO₂ Equivalent)
Includes 20% root allowance multiplier based on standard US Forestry metrics. Dry carbon equals approx. 50% of the dry wood content.
Forestry Scaling Reference Info
Standard forest diameter values are measured at DBH (4.5 feet / 1.37 meters aboveground). Cords of firewood represent stacked wood, which contains roughly 65% solid wood volume and 35% empty airspace gaps.
