- 1). 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.
- 2). 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.
- 3). Convert your square inches to square feet by dividing by 12. For instance, 12 square inches would equal one square foot.
- 4). Convert square feet to square meters by multiplying by 0.09294. Therefore, one board foot equals 0.09294 square meters.
