Gids & Inligting

Hoe om hierdie hulpmiddel te gebruik

  1. Globale Instellings: Kies jou meeteenheid (Metriek of Imperiaal), prys, en verwagte afvalpersentasie.
  2. Plankafmetings: Voer afmetings vir elke plank in. Die 3D-voorskou sal die vorm wys.
  3. Hersiening: Sien totale volume en beraamde koste in die opsommingstabel.

Wat is 'n Bordvoet?

'n Bordvoet (BF) is 'n eenheid van volume. 1 BF = 144 kubieke duim (12x12x1).

In die Metrieke stelsel bereken ons eenvoudig Kubieke Meter (m³).

Berekeningsformule

Imperiaal (BF):

(Thk_in × W_in × L_ft) ÷ 12

Metriek (m³):

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

*Bereken deur mm na meter om te skakel.

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.

Gereelde Vrae

Hoekom verskil my BF van die winkel s'n?

Houtwerwe bereken dikwels gebaseer op 'nominale' nat afmetings voor droging. Meet altyd die werklike plank.

Hoeveel afval moet ek byvoeg?

Vir skoon hout is 10-15% standaard. Vir ru-gesaagde of hout met kwaste, bereken 20-30%.
