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
