Calculate the basal area per acre with our free, easy-to-use Basal Area Calculator. This essential forestry tool helps landowners, foresters, and researchers quickly assess tree density and stand health. Simply input the Diameter at Breast Height (DBH) and Trees Per Acre (TPA) to determine critical metrics for sustainable forest management and timber valuation.
Formula:
Basal Area (sq ft/acre) = 0.005454 × DBH2 × TPA
- DBH: Diameter at Breast Height (inches)
- TPA: Trees Per Acre
- 0.005454: Conversion factor derived from (π / (12 inches/foot × 2)2)
