DBH / volume
Standing Tree Volume Calculator (DBH, Height, Form Factor, Saved Formulas)
Estimate standing tree volume from DBH, height, form factor, and formula presets.
Switch among m³, ft³, and board feet, and absorb regional differences by swapping formula presets.
DBH and height convert into one tree volume result
Formula presets handle regional standards
m³ / ft³ / board feet switching is built in
Save and share user-defined formulas
Swap formula presets to reflect regional, species, or company-specific standards.
Switch the result between m³, ft³, and board feet without changing the underlying calculation.
Save your own formulas in the browser and export or import them as JSON.

Glossary
FormulasDBH
Diameter at breast height. The stem diameter measured at the local breast-height convention.
Form factor
A coefficient that describes how much a trunk differs from a perfect cylinder.
Basal area
The stem cross-sectional area derived from DBH.
board feet
An equivalent display unit for cubic volume in this tool. It is not a local log rule.
Formula preset
A reusable formula template that carries its unit basis, coefficients, and notes.
Formulas
DBH / H / fG = π × (DBH / 2)^2V = G × H × fV = a × DBH^b × H^cV_bf = V_ft3 × 12
Important notes
Important notes
Board feet is an equivalent display unit in this tool. It is not the same thing as Doyle, Scribner, or International log rules.
DBH conventions vary by region and organization. Match the saved formula to the field standard you actually use.
Built-in formulas are reference templates. Replace them with your own measured standards whenever possible.
Saved formulas stay on this device unless you export them.
