1) MILD STEEL (MS) SHEET WEIGHT (KGS) = LENGTH (MM) * WIDTH (MM) * 0. 00000785 * THICKNESS example – The weight of MS Sheet of 1mm thickness and size 1250 MM * 2500 MM shall be 2500MM * 1250 MM * 0.00000785 * 1 = 24.53 KGS/ SHEET ————————————————— ROLLED STEEL CHANNELS MS SQUARE WEIGHT (KGS ) = WIDTH * WIDTH * 0.00000785 * LENGTH. Example : A Square of size 25mm and length 1 metre then the weight shall be. 25 * 25 * .00000785 * 1000mm = 4.90 kgs / metre

MS ROUND WEIGHT (KGS ) = 3.14 * 0.00000785 * ((diameter / 2)*( diameter / 2)) * LENGTH. Example : A Round of 20mm diameter and length 1 metre then the weight shall be. 3.14 * 0.00000785 * ((20/2) * ( 20/2)) * 1000 mm = 2.46 kgs / metre SS ROUND DIA (mm) * DIA (mm) * 0.00623 = WEIGHT PER METRE SS / MS Pipe OD ( mm) – W.Tthick(mm) * W.Thick (mm) * 0.0248 = Weight Per Metre OD ( mm) – W.Tthick(mm) * W.Thick (mm) * 0.00756 = Weight Per Foot

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

SS sheet Length (Mtr) * Width (Mtr) * Thick(mm) * 8 = Weight Per Piece Length (ft) * Width (ft) * Thick(inch) * 3 /4 = Weight Per Piece

S.S HEXAGONAL BAR DIA (mm) * DIA (mm) * 0.00680 = WT. PER Mtr Dia (mm) * Dia (mm) * 0.002072 = Wt. Per foot.

BRASS SHEET WEIGHT (KGS) = LENGTH (MM) * BREADTH (MM) * 0. 0000085 * THICKNESS EXAMPLE = THE WEIGHT OF BRASS SHEET OF THICKNESS 1 MM , LENGTH 1220 MM AND BREADTH 355 MM SHALL BE 1220 * 355 * 0.0000085 * 1 = 3.68 Kgs / Sheet

COPPER SHEET WEIGHT (KGS) = LENGTH (MM) * BREADTH (MM) * 0. 0000087 * THICKNESS EXAMPLE = THE WEIGHT OF BRASS SHEET OF THICKNESS 1 MM , LENGTH 1220 MM AND BREADTH 355 MM SHALL BE 1220 * 355 * 0.0000087 * 1 = 3.76 Kgs / Sheet BRASS / COPPER PIPE OD (mm) – THICK (mm) * THICK(mm) * 0.0260 = WEIGHT PER METRE

ALUMINIUM SHEET WEIGHT (KGS) = LENGTH (MM) * BREADTH (MM) * 0. 00000026 * THICKNESS EXAMPLE = THE WEIGHT OF ALUMINIUM SHEET OF THICKNESS 1 MM , LENGTH 2500 MM AND BREADTH 1250 MM SHALL BE 2500 * 1250 * 0.0000026 * 1 = 8.12 Kgs / Sheet

ALUMINIUM PIPE OD (mm) – THICK(mm) * THICK(mm) *0.0083 = WEIGHT PER METRE

Measurement Units

Civil engineers throughout the world accept both the United States Customary System (USCS) and the System International (SI) units of measure for both applied and theoretical calculations. However, the SI units are much more widely used than those of the USCS. Hence, both the USCS and the SI units are presented for essentially every formula in this website.

To permit even wider use of this text, this website contains the conversion factors needed to switch from one system to the other.
