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
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

sir please how can i calculate weight of a bag of load without using scale
Please 1220mm×width 2440mm length 17 mm thickness and 32 kg weight to density How much will it be?
Dear Sir,
Kidnly advise how the calculate the following
1) how many meter can draw from 1Mt 6.50mm wire rod
2) How to calculate the weight of Galvanised weld mesh 100x50x1.80x30mtr using 2.50mm galvanised wire
