Project Cost Summary
A Board Foot (BF) is a standardized unit of lumber volume in the United States and Canada. One board foot is equivalent to a volume of 12 in x 12 in x 1 in (144 cubic inches, or 1/12 of a cubic foot).
Note that rough-sawn hardwoods are measured in nominal dimensions (often expressed as quarters like 4/4, 5/4, 8/4) which are typically thicker than post-planed surfaced lumber.
