## Board Foot - the volume measurement of lumber

Sponsored Links

*Board foot* is a volume measurement of lumber, where

*1 board foot = 144 in*^{3}= 1⁄12 ft^{3}= 2360 cm^{3}= 2.360 liters = 0.002360 m^{3}

Board feet can be calculated as

BF = W T L / 12 (1)

where

BF = board feet

W = nominal lumber width (in)

T = nominal lumber thickness (in)

L = nominal lumber length (ft)

### Quick Approximation for Calculating Board Feet

- 1 x 4 - divide linear length (feet) by 3 - (length x 1/3)
- 1 x 6 - divide linear length (feet) by 2 - (length x 1/2)
- 1 x 8 - multiply linear length (feet) by 0.66 - (length x 2/3)
- 1 x 12 - linear length (feet) equals board feet - (length x 1)
- 2 x 4 - multiply linear length by 0.66 - (length x 2/3)
- 2 x 6 - linear length (feet) equals board feet - (length x 1)
- 2 x 8 - multiply linear length by 1.33 - (length x 1 1/3)
- 2 x 12 - multiply linear length by 2 - (length x 2)
