How to calculate the cost of metal using a calculator?

After determining the total weight (in kg or tons), multiply the result by the market price per unit weight of the selected metal.

How accurate are the calculations of the weight of rolled metal?

The error does not exceed 0.5% and is due to GOST tolerances for metal thickness. Standard densities are used for calculations (for example, 7850 kg/m³ for steel).

What types of metal can be counted?

Supported: black steel, stainless steel, aluminum, copper, brass, bronze, titanium and other alloys.

⚙️ How to use the tool

Select material:Steel, aluminum, copper, cast iron, titanium, etc.
Specify the shape: Select the type of profile (pipe, angle, sheet, channel, fittings).
Enter dimensions: Fill in the fields (length, width, wall thickness) in millimeters.
Result:Get your exact weight in kilograms and tons instantly.

📋 Supported rental types

1. Rolled sheets

Steel and aluminum sheets, plates, strips. Indispensable for calculating cladding and roofing.

2. Pipes

Round (VGP), profile (square and rectangular). The outer diameter and wall thickness are taken into account.

3. Long products

Reinforcement, circle, square, hexagon, as well as shaped products (angle, channel, beam).

📐 Reference

🧪 Metal density table (kg/m³)

The calculator uses reference density values for maximum accuracy:

Steel (st3): 7850 kg/m³
Stainless steel (12Х18Н10Т): 7900 kg/m³
Aluminium: 2700 kg/m³
Copper: 8960 kg/m³
Brass: ~8500 kg/m³ (depending on brand)
Titanium: 4500 kg/m³

📐 Weight calculation formulas

To check the calculations manually:

Sheet: Weight = Length × Width × Thickness × Density

Round pipe: Weight = π × (R² - r²) × Length × Density
(where R is the outer radius, r is the inner)

Profile pipe: Weight = (A×B - (A-2t)×(B-2t)) × Length × Density

❓ Frequently asked questions (FAQ)

🔹 How to find out the cost of a batch of metal?

First, calculate the total weight of the batch using our calculator. Then multiply the resulting weight (in tons) by the current price per ton from your supplier.

🔹 How accurate is the calculation?

The error is less than 0.5% and depends only on GOST for rental (wall thickness tolerances). For household and construction needs, the accuracy is absolute.

🔹 How to calculate the weight of a complex part?

Break a complex structure into simple elements (angles, plates, pipes). Calculate the weight of each element separately and add up the results. If you need other tools, check out our sitemap.
