Common questions about walnut weight.
How to Calculate
Enter your walnut board dimensions (length, width, thickness) in feet or inches, and specify the quantity. The calculator multiplies the volume by black walnut's density of 38 lb/ft³ to determine weight. **Formula: Weight = Length × Width × Thickness × Density × Quantity**. Convert all dimensions to feet first, then multiply by 38 to get pounds. This works for both rough-sawn and surfaced lumber, though actual weights may vary by 5-10% based on moisture content and wood origin.
Formula & Method
Weight (lbs) = Length (ft) × Width (ft) × Thickness (ft) × 38 lb/ft³ × Quantity
For inches: Convert to feet by dividing by 12, then apply formula.
