## Core Calculators & Web Tools

- **Main Board Foot Calculator**: [Board Foot Calculator](https://www.bdftcalculator.com/)
  - Formula: Board Feet = (Thickness in inches × Width in inches × Length in feet) / 12
  - Multi-piece lumber estimation with species density and pricing models.
- **Lumber Volume Calculator**: [Lumber Calculator](https://www.bdftcalculator.com/lumber-calculator/)
  - Dimensional lumber volume estimations for 2x4, 2x6, 2x8, 2x10, 4x4, 6x6.
- **Wood Weight & Density Calculator**: [Wood Weight Calculator](https://www.bdftcalculator.com/weight-calculator/)
  - Calculates green weight, kiln-dried weight, and oven-dry weight across 50+ hardwood and softwood species.
- **Log Scaling Calculator**: [Logs Calculator](https://www.bdftcalculator.com/logs-calculator/)
  - Log volume scaling using Doyle Log Rule, Scribner Dec C Log Rule, and International 1/4" Log Rule.
