Total Board Feet vs Thickness (nominal)
公式
## How to Calculate Lumber ### Board Foot Formula **Board Feet = (Thickness × Width × Length) / 12** Thickness and width are in inches (nominal), length is in feet. One board foot is a piece 1 inch thick × 12 inches wide × 12 inches long (or 144 cubic inches). Hardwood lumber is priced by the board foot, while dimensional softwood lumber is often priced per linear foot or per piece.
计算示例
20 pieces of 2×6 lumber, 12 ft long, at $5 per board foot.
- 01Board feet per piece = (2 × 6 × 12) / 12 = 12 BF
- 02Total board feet = 12 × 20 = 240 BF
- 03Total linear feet = 12 × 20 = 240 lin ft
- 04Cost = 240 × $5 = $1,200.00
常见问题
What is a board foot?
A board foot (BF) is a unit of volume equal to 144 cubic inches: 1 inch thick × 12 inches wide × 12 inches long. It is the standard unit for pricing hardwood lumber.
What is the actual size of a 2×6?
A nominal 2×6 is actually 1.5 × 5.5 inches. However, board foot calculations use the nominal (named) dimensions, not the actual dimensions.
How do I convert linear feet to board feet?
Multiply linear feet by the nominal thickness and width, then divide by 12. For a 2×6: BF = linear feet × 2 × 6 / 12 = linear feet × 1.
