Conversion Formulas

All calculations based on net footages

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

Price/m fbm into price/lf

Price/M ÷ 12 x Width x Thickness ÷ 1000 = Price/LF

lineal footage (LF)FBM

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/LF into Price/M FBM

Price/LF x 12 ÷ Width ÷ Thickness x 1000 = Price/M
