Understanding the Board Foot (Lumber) Converter

The board foot is the traditional unit of the North American lumber trade, equal to a piece of wood one foot square and one inch thick — 144 cubic inches. It lets sawmills and lumberyards price boards of many different dimensions on a single volume basis, and has been the industry standard for well over a century.

Woodworkers, builders and timber buyers convert board feet to and from cubic feet, cubic metres and cords when estimating material, comparing quotes, or working from metric plans. This converter handles all of those so you can budget a project or check a delivery without manual arithmetic.
