FORMULA OF WEIGHT

WEIGHT OF STAINLESS & CARBON STEEL PIPES & TUBES O.D. (mm) – W.T. (mm) x W.T. (mm) X 0.02466 = Kg. Per Meter
SHEET WIDTH REQUIRED FOR ROLLED AND WELDED PIPES O.D. (mm) – Thk. (mm) X 3.14 = Sheet Width
WEIGHT OF STAINLESS STEEL SHEETS Length (Mtr.) x Width (Mtr.) x Thk. (mm) x 8 = Kg. Per Sheets
WEIGHT OF STAINLESS STEEL CIRCLE & BLANKS O.D. (mm) X O.D. (mm) X Thk. (mm) – 16000 = Kg. Per Pcs.
WEIGHT OF STAINLESS STEEL ROUND Dia. (mm) x Dia. (mm) x 0.00623 = Kg. Per Meter
WEIGHT OF STAINLESS STEEL HEXAGONAL RODS Dia (mm) x Dia. (mm) x 0.00679 = Kg. Per Meter
WEIGHT OF STAINLESS STEEL SQUARE BARS Dia. (mm) x Dia. (mm) x 0.00787 = Kg. Per Meter
WEIGHT OF COPPER PIPES O.D. (mm) – W.T. (mm) x W.T. (mm) x 0.0256 = Kg. Per Meter
WEIGHT OF LEAD PIPES (APPROX) O.D. (mm) – W.T. (mm) x W.T. (mm) x 0.0345 = Kg. Per Meter
WEIGHT OF LEAD SHEETS (APPROX) Length (Mtr.) x Width (Mtr.) x Thk. (mm) x 11.2 = Kg. Per Sheet
WEIGHT OF ALUMINIUM PIPES (APPROX) O.D. (mm) – W.T. (mm) x W.T. (mm) x 0.0082 = Kg. Per Sheet
WEIGHT OF ALUMINIUM SHEETS (APPROX) Length (Mtr.) x Width (Mtr.) x Thk (mm) x 2.66 = Kg. Per Sheet
 
Tensile Strength Conversion Table
1) Kg/mm2 x 9.81 = N/mm2 = Mpa
2) Psi x 0.0007 = Kg/mm2
3) Ksi x 1000 = Psi
4) Kg/mm2 x 1.422 = Ksi
