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
Example – The weight of coppper sheet of thickness 1 mm, length 1220mm and breadth 355mm shall be
1220X355 X 0.0000087 X 1 = 3.76 Kgs/Sheet
BRASS / COPPER PIPE
OD (mm) – THICK (mm) X THICK(mm) X 0.0260 = WEIGHT PER METRE
ALUMINUM SHEET
WEIGHT (KGS) = LENGTH (MM) X BREADTH (MM) X 0. 00000026 X THICKNESS
Example – The weight of Aluminum sheet of thickness 1 mm, length 2500mm and breadth 1250 mm shall be
2500x1250X 0.0000026 X 1 = 8.12 Kgs/Sheet
ALUMINIUM PIPE
OD (mm) – THICK(mm) X THICK(mm) X0.0083 = WEIGHT PER METRE
