Glossary

Formulas
DBH

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 / f
  1. G = π × (DBH / 2)^2
  2. V = G × H × f
  3. V = a × DBH^b × H^c
  4. V_bf = V_ft3 × 12

Маанилүү эскертүүлөр

Маанилүү эскертүүлөр
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.
