Mwongozo na Habari

Jinsi ya Kutumia Zana Hii

  1. Mipangilio ya Jumla: Chagua mfumo wako wa vipimo (Kipimo au Kifalme), bei, na asilimia ya mabaki inayotarajiwa.
  2. Vipimo vya Ubao: Weka vipimo kwa kila ubao. Onyesho la 3D litaonyesha umbo.
  3. Mapitio: Angalia jumla ya ujazo na gharama iliyokadiriwa kwenye jedwali la muhtasari.

Mguu wa Ubao (Board Foot) ni nini?

Mguu wa Ubao (BF) ni kipimo cha ujazo. 1 BF = inchi 144 za ujazo (12x12x1).

Katika mfumo wa Kipimo, tunakokotoa Mita za Ujazo (m³) tu.

Fomula za Hesabu

Kifalme (BF):

(Thk_in × W_in × L_ft) ÷ 12

Kipimo (m³):

(Thk_mm × W_mm × L_mm) ÷ 1,000,000,000

*Inakokotolewa kwa kubadilisha mm kuwa mita.

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.

Maswali ya Kawaida

Kwa nini BF yangu ni tofauti na dukani?

Yadi za mbao mara nyingi huhesabu kulingana na vipimo 'vya kawaida' vya mbao mbichi kabla ya kukausha. Pima ubao halisi kila wakati.

Niongeze mabaki kiasi gani?

Kwa mbao safi, 10-15% ni kawaida. Kwa mbao chafu au zenye mafundo, hesabu 20-30%.
