Steps to Use a Steel Weight Calculator

1. Select the Shape of the Steel:

  • Choose the shape of the steel you are calculating the weight for. Common shapes include:
    • Round Bar
    • Square Bar
    • Rectangular Bar
    • Circular Tube
    • Square Tube
    • Rectangular Tube
    • Sheet/Plate

2. Input Dimensions:

  • For Bars and Tubes:
    • Length: Enter the length of the steel piece.
    • Diameter (for round bar) or Width and Height (for square/rectangular bar and tubes): Enter the respective dimensions.
    • Wall Thickness (for tubes): If applicable, enter the wall thickness.
  • For Sheets/Plates:
    • Length and Width: Enter the length and width of the sheet or plate.
    • Thickness: Enter the thickness of the sheet or plate.

3. Select or Input the Material Density:

  • Many calculators have a default density for steel, typically around 7850 kg/m³ or 490 lb/ft³. Ensure the correct density is selected if you’re using a specific type of steel.

4. Calculate the Weight:

  • Click the calculate button to get the weight of the steel piece. The calculator will use the volume of the steel (based on dimensions) and the density to compute the weight.

Example of Using Steel Weight Calculator


Let’s go through an example calculation for a steel rectangular bar:

  1. Shape: Rectangular Bar
  2. Dimensions:
    • Length: 2 meters
    • Width: 0.1 meters
    • Height: 0.05 meters
  3. Density: 7850 kg/m³ (standard for steel)

Using the formula: Weight=Volume×Density

First, calculate the volume: Volume=Length×Width×Height Volume=2 m×0.1 m×0.05 m Volume=0.01 m3

Then, calculate the weight: Weight=0.01 m3×7850 kg/m3 Weight=78.5 kg

The weight of the rectangular steel bar is 78.5 kg.

Tips of Using Steel Weight Calculator

  • Always double-check the units used (metric or imperial) to ensure accuracy.
  • For complex shapes or assemblies, break down the calculation into simpler parts and sum their weights.
  • Consult the calculator’s help or documentation section if available for specific instructions or tips related to the tool.


By following these steps, you should be able to accurately determine the weight of various steel components for your projects.
