FORMULA OF CALCULATING WEIGHT

Quick reference guide for calculating the weight of various metal pipes, sheets, tubes, and rods.

Weight of Stainless Steel / Carbon Steel Pipes & Tubes

OD (mm) - W.T. (mm) X W.T. (mm) X 0.02466 = KG. / MTR.

Weight of Aluminum Pipes

O.D. (mm) - W.T. (mm) x W.T. (mm) x 0.0282 = KG. / MTR.

Weight of Stainless Steel Sheets

Length (mm) x Width (mm) x Thk. (mm) x 0.000008 = KG. / SHEET

Weight of Aluminum Sheets

Length (mtr.) x Width (mtr.) x Thk. (mm) x 2.66 = KG. / SHEET

Weight of Carbon Steel Sheets

Length (mm) x Width (mm) x Thk. (mm) x 0.000008 = KG. / SHEET

Weight of Lead Sheets

Length (mtr.) x Width (mtr.) x Thk. (mm) x 11.2 = KG. / MTR.

Weight of Stainless Steel Circle & Blanks

O.D. (mm) x O.D. (mm) x Thk. (mm) x 0.0000063 = KG./PCS.

Sheet Width Reqd. For Rolled & Welded Pipes

O.D. (mm) - Thk. (mm) x 3.14 = SHEET WIDTH (mm)

Weight of Stainless Steel Rounds

Dia. (mm) x Dia. (mm) x 0.00623 = KG. / MTR.

Weight For Square / Rectangle Pipes

Length from 4 Angle (OD) / 3.14 - Thk. (mm) x Thk. (mm) x 0.00756 = KG. / PER FEET

Weight of Stainless Steel Hexagonal Rods

Dia.(mm) x Dia. (mm) x 0.00679 = KG. / MTR.

Weight For Conversion of Mtr. to Feet

Weight of 1 Mtr. ÷ 3.2808 = Feet

Weight of Stainless Steel Square Rods

Dia. (mm) x Dia. (mm) x 0.00787 = KG. / MTR.

Weight of Copper Pipes

O.D. (mm) - W.T. (mm) x W.T. (mm) x 0.0285 = KG. / MTR.

Formula For Healthy Business

Honesty + Quality of Goods + Quick Service + Reasonable rate = Good Health of Business
