Weight of S.S. Flate Bar

Width (mm ) X Thick ( mm ) X 0.00798 = Wt.Per Mtr.

Width (mm ) X Thick ( mm ) X 0.00243 = Wt.Per Feet.

Weight of Brass Pipe / Copper Pipe

O.D. ( mm ) – Thick ( mm ) X Thick (mm ) X 0.0260 = Wt. Per Mtr.

Weight of Lead Pipe.

O.D. ( mm ) – Wt ( mm ) X Wt ( mm ) X 0.0345 = Wt. Per Mtr.

Weight of Aluminium Pipe

O.D. ( mm ) – Thick ( mm ) X Thick ( mm ) X 0.0083 = Wt.Per. Mtr.

Weight of Aluminium Sheet

Length ( Mtr ) X Width ( Mtr ) X Thick ( mm ) X 2.69 = Wt.Per PC

Weight of Conversion of Mtr to Feet

Wt of 1 Mtr. 3.2808 = Wt.Per Feet.

Barlow’s Formula for calculating bursting pressure

P = 2ST/Dort – DP/2S or S – DP/2t or D = 2st/p

P = Bursting Pressure P. si.

S = Tensile Strength of tube.

T = Well Thickness ( In Inches )

D = Outside diameter ( In Inches )

Standard conversion factors INCH = 25.4 MILLIMETRE

FOOT = 0.3048 METRE

YARD = 0.9144 METRE

MILE = 1.6093 KILOMETER

ACRE = 0.4047 HECTARE

POUND = 0.4536 KILOGRAM

DEGREE FARENHEIT X 5/9 – 32 = DEGREE CELSIUS

MILLIMETRE= 0.0394 INCH

METRE = 3.2808FOOT

METRE = 1.0936YARD

1) MILD STEEL (MS) SHEET

WEIGHT (KGS) = LENGTH (MM) X WIDTH (MM) X 0. 00000785 X THICKNESS

example – The weight of MS Sheet of 1mm thickness and size 1250 MM X 2500 MM shall be

2500MM X 1250 MM X 0.00000785 X 1 = 24.53 KGS/ SHEET

ROLLED STEEL CHANNELS

MS SQUARE WEIGHT (KGS ) = WIDTH X WIDTH X 0.00000785 X LENGTH.

Example : A Square of size 25mm and length 1 metre then the weight shall be.

25x25X 0.00000785 X 1000mm = 4.90 kgs/metre

MS ROUND WEIGHT (KGS ) = 3.14 X 0.00000785 X ((diameter / 2)X( diameter / 2)) X LENGTH.

Example : A Round of 20mm diameter and length 1 metre then the weight shall be.

3.14 X 0.00000785 X ((20/2) X ( 20/2)) X 1000 mm = 2.46 kgs / metre

SS ROUND DIA (mm) X DIA (mm) X 0.00623 = WEIGHT PER METRE

SS / MS Pipe

OD ( mm) – W.Tthick(mm) X W.Thick (mm) X 0.0248 = Weight Per Metre

OD ( mm) – W.Tthick(mm) X W.Thick (mm) X 0.00756 = Weight Per Foot

SS / MS CIRCLE DIA(mm) X DIA (mm) X THICK(mm) 0.0000063 = Kg Per Piece

SS sheet Length (Mtr) X Width (Mtr) X Thick(mm) X 8 = Weight Per Piece

Length (ft) X Width (ft) X Thick(inch) X 3 /4 = Weight Per Piece

S.S HEXAGONAL BAR DIA (mm) X DIA (mm) X 0.00680 = WT. PER Mtr

Dia (mm) X Dia (mm) X 0.002072 = Wt. Per foot.

BRASS SHEET WEIGHT (KGS) = LENGTH (MM) X BREADTH (MM) X 0. 0000085 X THICKNESS

Example – The weight of brass sheet of thickness 1 mm, length 1220mm and breadth 355mm

shall be

1220 X355X 0.0000085 X 1 = 3.68 Kgs/Sheet

COPPER SHEET WEIGHT (KGS) = LENGTH (MM) X BREADTH (MM) X 0. 0000087 X THICKNESS
