A cubic foot of steel weighs about 490 pounds. The metal weighs 0.2904 pounds per cubic inch. Steel weight formulas are based on theoretical nominal weights and only give approximate values.
Continue ReadingA 1-inch-square steel bar weighs about 3.40 pounds per lineal foot. The weight of a round steel bar in pounds per lineal inch is given by 0.22 times the diameter squared. The weight of square bar in pounds per lineal inch is 0.28 times the length of one of its sides squared. If the bar is flat, calculate its weight per lineal inch with the equation 0.28 x width x thickness.
