A board foot is a unit of measurement used in the lumber industry to quantify the volume of wood. It is defined as a volume of one foot long, one foot wide, and one inch thick, which equals 144 cubic inches. Board feet are commonly used to measure large quantities of lumber, making it easier to calculate costs and pricing for timber products.
