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

Detailed Units – Convert Units

Following table shows how can we convert various most commonly used units from one unit system to another.

Units to convert

Value

Square foot to Square meter

1 ft² = 0.092903 m²

Foot per second squared  to Meter per second squared

1 ft² = 0. 3048 m²

Cubic foot to  Cubic meter

1 ft³ = 0.028316 m³

Pound per cubic inch to Kilogram per cubic meter

1 lb/in³ = 27679.9 047102 kg/m³

Gallon per minute = Liter per second

1 Gallon per minute = 0.0631 Liter per second

Pound per square inch = Kilopascal

1 Psi (Pound Per Square Inch)  = 6.894757  Kpa (Kilopascal)

Pound force = Newton

1 Pound force = 4.448222 Newton

Pound per Square Foot to Pascal

1 lbf/ft2 = 47.88025 Pascal

Acre foot per day = Cubic meter per second

1 Acre foot per day= 1428 (m3/s)

Acre to square meter

1 acre = 4046.856 m²

Cubic foot per second = Cubic meter per second

1 ft³/s = 0.028316847 m³/s

Measurement Units

Measurement units and standards are different in different countries but to maintain a standard, SI units are mostly used when dealing with projects involving different countries or even different states. Small projects can be done with the locally used unit system but when the project is big, one standard unit system is to be used.

Two most common system used in the United States are

United States Customary System (USCS)
System International (SI)

But the SI unit system is more widely used all over the world. Following is the table which shows how you can convert USCS measurements in SI measurements. ( Just multiply the USCS amount with the corresponding figure given in table below

Convert USCS into SI Units

USCS unit X Factor = SI unit SI symbol
Square foot X 0.0929 = Square meter M2
Cubic foot  X 0.2831 = Cubic meter M3
Pound per square inch X 6.894 = Kilopascal KPa
Pound force X 4.448 =  Newton Nu
Foot pound torque X 1.356 = Newton meter N-m
Kip foot X 1.355 = Kilonewton meter LN-m
Gallon per minute X 0.06309 = Liter per second L/s
Kip per square inch X 6.89 = Megapascal MPa
