Doyle: (D−4)²×L / 16; Scribner: (0.79D²−2D−4)×L/16 — where D is the small-end diameter inside bark (in) and L the log length (ft). Per-tree volume is computed log by log, applying your taper to each 16 ft log and stopping at the minimum top diameter. Expansion factor = 43,560 / (π×r²). Board-foot estimates vary by rule and local practice; confirm with a paid scale before buying or selling stumpage.
