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
