Weight of steel calculator formula: bar, sheet, pipe & plate

The steel weight calculator allows you to calculate an estimate of the weight of different types of steel materials such as steel plate, bar, sheet, tube, tank, pipe and more based on dimensions and shape. Its allows you to calculate weight of steel in metric (kg) or Imperial system in lbs.

The steel is most commonly used construction materials worldwide in many forms. Weight of steel calculation is not only crucial for constructions, it is also needed in the transport sector and for lifting equipment.

Steel weight calculator will help you determine the weight of steel pieces of any size, whether rods, tube, tank, pipe, bars, or plates. This calculator to work with a variety of steel types, so you’ll get the steel weight you need.

Steel is a metal alloy formed from mixing of iron and small amount of carbon, iron as its main component and carbon as its primary alloying element. If carbon makes up anywhere from 0.05% to a little above 2% of the total weight of steel, the iron is stronger and more ductile. The more carbon we add to iron, the stronger the steel gets (up to 2.14% carbon). Adding other alloying elements results in four major steel types – carbon steel, alloy steel, stainless steel, and tool steel.

We see many steel products almost everywhere, from our kitchen utensils to the rebars at the construction site or round pen for our animals.

Steel material can be molded, machined, or combined with other materials to form almost any product we can imagine. In construction, steel is available in rods, tubes, wires, plates, and sheets. We can use steel rods as pins to connect hinged supports in steel frames and structures.

Generally price of steel decided by per unit weight or per unit length in the construction industry, similar to other raw materials like gravel, sand, and concrete. Since steel is available in various types, shapes, and sizes, pricing steel per unit weight would mean much more consistent pricing across the market.

Other than that, determining the total weight of steel products is generally beneficial, especially during transport. Buying in bulk affects the cost of most materials as we can save money by adequately organizing delivery and logistics instead of delivering small quantities on multiple trips. Aside from that, since steel can get really heavy in large volumes, calculating the steel weight is essential in the design of structures.

Weight of steel calculator formula- how to calculate weight of steel

Determining the weight of steel only takes a few steps to accomplish. First, we need to know the density of steel alloy we are using and the next step is to obtain the total volume of our steel by multiplying length by width by height, multiply both volume and density of steel, you will get weight of steel with the help of weight of steel calculator.

Formula for weight of steel calculation:

Ws = Vs × density of steel

Vs = l/1000 × w/1000 × t/1000,

Density of steel = 7850kg/m3

Where,
● Ws = weight of steel,
● l = length in mm
● w = width in mm
● t = depth in mm
● Ds = density of steel (7850kg/m3)

When using this formula, always make sure to multiply values with the same units of measurement. The resulting unit of measure of the volume must match the volume part in the density unit also.

Weight of Steel calculator formula/ weight of Steel calculation formula are following:-

● Round/ circular solid bars = D^2 × 0.006165 kg/ m

● Round/ circular solid bars = D^2 × 0.001876 kg/ ft

● Round/ circular solid bars = D^2 × 0.004143 lbs/ ft

● Hexagonal solid bars = D^2 × 0.006798 kg/m

● Hexagonal solid bars = D^2 × 0.006165 lbs/ft

● Square shaped solid bars = (size in mm)^2 × 0.00785 kg/m

● Square shaped solid bars = (size in mm)^2 × 0.00527 lbs/ ft

● Weight of rectangular metal sheet = length × width × thickness × density

Weight of steel calculator lbs

If you want to estimate weight of steel in US based Imperial measurements system in lbs, you should use steel weight calculator formula: 1) (size in mm)^2 × 0.00527 lbs/ ft for square shaped solid bars, and 2) D^2 × 0.006165 lbs/ft for hexagonal solid bars.

Steel sheets and plates are typical available in 36”, 48”, and 60” widths and 96”, 120”, and 144” lengths.

Example – Weight of Steel Plate
The weight of a 1 inch thick, 36″ (3 ft) width x 96″ (8 ft) long steel plate with weight 40.8 lb/ft2 can be calculated as

W = (40.8 lb/ft2) × (3 ft) × (8 ft)

= 979lb (pounds),

Calculating Steel Plate Weight
Weight per sq. feet of hot rolled mild steel plates can be calculated as

W = 40.8 t

Where,

W = weight of steel plate (lb/ft2)

t = plate thickness (in).

Weight of steel calculator metric

If you want to estimate weight of steel in metric system in kg, you should use steel weight calculator formula: 1) weight of round/ circular solid bars = D^2 × 0.006165 kg/ m, and 2) weight of round/ circular solid bars = D^2 × 0.001876 kg/ ft

For example:- calculate the weight of round solid bar of dimension 10mm bar of 12m length

Given, length of bar = 12 meter
Dia of bar = 10mm

Weight of round bar = 10×10×12×0.006165 = 7.4kg or 16.3lbs.

Weight of steel plate calculator

Steel sheets and plates are typical available in 36”, 48”, and 60” widths and 96”, 120”, and 144” lengths. Weight of steel plate calculator formula: W = (40.8 lb/ft2) × width × length, are used for 1 inch thick steel plate

For example – The weight of a 1 inch thick, 47″ (4 ft) width x 120″ (10 ft) long steel plate with weight 40.8 lb/ft2 can be calculated as

W = (40.8 lb/ft2) × (4 ft) × (10 ft)

= 1,632lb (pounds),

Calculating Steel Plate Weight
Weight per sq. feet of hot rolled mild steel plates can be calculated as

W = 40.8 t

Where,

W = weight of steel plate (lb/ft2)

t = plate thickness (inch).

Unit weight of steel bars: (8mm, 10mm, 12mm, 16mm & 20mm)

How far can a 6 inch, 4″, 8″, 10″ & 12 inch steel i beam span

What size steel beam for 32 feet span

What size steel beam for 30 feet span

What size steel beam for 26 feet span

Weight of steel bar calculator

Weight of round or circular solid steel bar can be calculated with the help of weight of steel bar calculator formula: 1) weight of round/ circular solid bars = D^2 × 0.006165 kg/ m, where D is dia of steel bar in mm.

For example: calculate the weight of round solid bar of dimension 12mm bar of 12m length

Given, length of bar = 12 meter
Dia of bar = 12mm

Weight of round bar = 12×12×12×0.006165 = 10.65kg or 23.48lbs.

Weight of Steel calculation formula- D^2 × 0.006165 kg/ m, where D is dia of steel bar in mm. By using this formula you can calculate different steel bar weight such as:-

● 8mm steel bar = 0.395 kg/m
● 10mm steel bar = 0.617 kg/m
● 12mm steel bar = 0.888 kg/m
● 16mm steel bar = 1.580 kg/m
● 20mm steel bar = 2.469 kg/m
● 25mm steel bar = 3.858 kg/m

Weight of steel pipe calculator

Pipe Weight Formula:- Wt/ft = 10.69 (OD _ wall thickness) × total length, this formula can be used to determine the weight per foot for any size of pipe with any wall thickness.

Conclusions:-

The steel weight calculator formula: Ws = Vs × density of steel, allows you to calculate an estimate of the weight of different types of steel materials such as steel plate, bar, sheet, tube, tank, pipe and more based on dimensions and shape.
