A board foot is a unit of volume equivalent to 144 cubic inches. To find tons, you would need to know the density of the particular wood that you are interested in.
====================================================
Boardfeet is based upon nominal dimensions. For example the nominal dimensions of a 2x4 is 2" x 4". It's actual dimension is closer to 1 1/2 inches x 3 1/2 inches. So there will be some error in the calculation if you are attempted to determine the weight of dimensional lumber. Southern Pine weights approximately 40 lbs per cubic foot. There are 1728 cubic inches in a cubic foot. There are 2000 lbs in a ton. therefore the weight of one board foot (conservatively because of the nominal dimensions) is:
(40x144)/(1728x2000) tons per board foot.
Sorry , don't have a calculator handy.
Another way to do it is that there are about 12 board feet in a cubic foot. So a board foot would weight 40/12 lbs or 3.33 pounds.
3.33 pounds is 3.33/2000 tons. !! a lot easier!!

To convert board feet to tons, you need to know the density of the wood you are dealing with. Typically, the density of wood is around 40 to 50 pounds per cubic foot. You can use this density value to calculate the weight in pounds and then convert to tons by dividing by 2000 (since 1 ton is equal to 2000 pounds).
One Cord equals 500 Board Feet 2,500 board feet / 500 = 5 cords CORDS TO BOARD FEET 5 (cords) x 500 = 2,500 board feet BOARD FEET TO TONS
To convert 2.66 tons per cubic meter to tons per cubic feet, you first need to convert cubic meters to cubic feet. There are approximately 35.3147 cubic feet in 1 cubic meter. Once you have the conversion factor, multiply the given value (2.66 tons per cubic meter) by the conversion factor to get the equivalent value in tons per cubic feet.
To convert board feet to lineal feet, divide the total board feet by the board's thickness in feet. For example, if you have 100 board feet of lumber that is 1 inch thick, you would divide 100 by 1, which equals 100 lineal feet.
To convert metric tons (tonnes) to net tons, simply divide the metric tons by 1.10231. This will give you the equivalent weight in net tons. For example, 10 metric tons is approximately equal to 9.07 net tons.
To convert 3.5 tons to pounds, you would multiply 3.5 by 2000 (since there are 2000 pounds in one ton). So, 3.5 tons is equal to 7000 pounds.
To convert pounds to dry tons, divide the weight in pounds by 2000, since there are 2000 pounds in a dry ton. For example, to convert 46660 pounds to dry tons: 46660 pounds / 2000 = 23.33 dry tons.
