You will find below a few conversion formulas and lumber weight information which we hope you'll find helpful.
Conversion Formula
-
- Board Footage (FBM)
- FBM = LF x Width ÷ 12 x Thickness
- Example: To convert 3000 LF of 8" x 1.25";
calculate 3000 x 8 ÷ 12 x 1.25 = 2500 FBM
- Lineal Footage (LF)
- LF = FBM ÷ Width x 12 ÷ Thickness
- Example: To convert 1500 FBM of 6" x 1.5";
calculate 1500 ÷ 6 x 12 ÷ 1.5 = 2000 LF
Price/M FBM into Price/LF
Price/M ÷ 12 x Width x Thickness ÷ 1000 = Price/LF
Price/LF into Price/M FBM
Price/LF x 12 ÷ Width ÷ Thickness x 1000 = Price/LF
All calculations based on net footages.
