The number of board feet contained in sawed lumber is calculated using this formula: Board feet = [thickness (inches) × width (inches) × length (feet)]/12. For example, a 12footlong piece of 2inch by 6inch construction lumber contains 12 board feet: 12 = [2 × 6 × 12]/12. Figure 14. One board foot of wood.

As used in these formulas the specific gravity of the ore is obtained simply by weighing a liter of mill pulp, then drying and weighing the ore. With these two weights formula (2) may be used to obtain K, and then formula (1) to convert to S, the specific gravity. A volumetric flask of one liter capacity provides the necessary accuracy.
