Calculating Weights
[ CLOSE ]
 You might need to calculate weights to determine the weight of a load on a delivery truck. In order to calculate weights you must first be able to calculate board footage. Weight tables are often listed as the weight per thousand board/square feet for a specific product category. To calculate the weight you multiply the total footage times the weight per board foot. To do this you must first convert the weight per thousand board feet to the weight per board foot. SPF (Spruce-Pine-Fir) lumber weighs approximately 1,650 pounds per thousand board feet. To calculate the weight of 360 PCS of 2x8-14 SPF you first calculate the board footage: 360 X 2 X 8 X 14 / 12 = 6,720 BFT Next convert the weight per thousand to the weight per board foot: 1,650 / 1000 = 1.650 Then calculate the weight: 6,720 X 1.65 = 11,088#. The weight for sheet goods is usually stated as the weight per thousand square feet. To calculate weight first determine the total square footage in each sheet. For a 66-piece unit of 4' X 8' waferboard panel: 66 X 32 = 2,112 SQUARE FEET Then multiply the total square footage times the weight per square foot for the product. 7/16" wafer panel weighs about 1,550 pounds/m. 2,112 X 1.550 = 3,273.6 POUNDS.
