A board foot is a standard measurement of lumber that indicates the length, width and thickness of a board that equals a total of one square foot. Many lumber companies sell lumber in terms of board feet. If you are using lumber for a project and dealing with metric measurements, you may need to convert board feet to square meters.
Determine the dimensions of the board feet. You could have various possibilities that equal one square foot, such as a board that is one inch thick, 12 inches long and one inch wide. Another possibility is a board that is six inches long, two inches wide and one inch thick.
Multiply the length times the width of the boards. For example, if have a board that is six inches long by two inches wide, you would have 12 square inches.
Convert your square inches to square feet by dividing by 12. For instance, 12 square inches would equal one square foot.
Convert square feet to square meters by multiplying by 0.09294. Therefore, one board foot equals 0.09294 square meters.
