WEIGHT CALCULATIONS FORMULAE AND CONVERSION FACTORS To calculate the weight of steel bars:

ROUND - dia.mm2 x 0.006165 = Weight in kilograms per metre ROUND - dia.mm2 x 0.004143 = Weight in lbs. per foot HEXAGON - size mm2 x 0.006798 = Weight in kilograms per metre HEXAGON - size mm2 x 0.00457 = Weight in lbs. per foot SQUARE - Size mm2 x 0.000785 = Weight in kilograms per metre SQUARE - Size mm2 x 0.00527 = Weight in lbs. per foot Feet to metres x 0.3048 Metres to feet x 3.2809 U.K. tons per sq. inch (tons f/in2) x 15.4443 = Mega Pascals (MPa) Mega Pascals (MPa) x 0.64749 = U.K. tons f per square inch Newton per sq. milimeter (N/mm2) x 0.064749 = U.K. tons per sq. inch
