指南与信息
什么是板材英尺 (Board Foot)?
板材英尺 (BF) 是体积单位。1 BF = 144 立方英寸 (12x12x1)。
在公制系统中，我们只需计算立方米 (m³)。
计算公式
英制 (BF):
(Thk_in × W_in × L_ft) ÷ 12公制 (m³):
(Thk_mm × W_mm × L_mm) ÷ 1,000,000,000*通过将毫米转换为米来计算。
Practical examples
One shelf board: A 1 in x 12 in x 6 ft board is 6 BF. At $5 per BF with 10% waste, the estimate is $33.
Metric hardwood order: A 25 mm x 150 mm x 2400 mm board is about 0.009 m³, or 3.8 BF before waste.
Common mistakes
Mixing length units: In imperial mode, length is in feet while thickness and width are in inches. If all three values are inches, the result will be 12 times too high.
Using nominal size by accident: Board-foot pricing often follows nominal lumber size. For a shop estimate, measure the actual board when that is what you will cut.
Forgetting waste: Add extra material for trimming, defects, grain choice, and mistakes. Raise the waste allowance for rough or figured boards.
Tips
Keep rough and surfaced boards separate: They may be priced or measured differently. Add them as separate rows so the list is easier to check.
Save before comparing options: Save one calculation, change the species or waste allowance, then save the new version for a quick side-by-side check.
常见问题
为什么我的 BF 与商店的不同？
木材场通常在干燥前根据“标称”生材尺寸计算。请务必测量实际板材。
我应该添加多少损耗？
对于净木材，标准是 10-15%。对于粗锯或有纹理的木材，计算 20-30%。
