Hollow Tube Weight Calculator (Steel, Aluminum)

Calculate the Weight of Hollow Tubing

Our Hollow Tube Weight Calculator is a precision tool for engineers, fabricators, and designers who need to determine the weight of hollow cylindrical sections. This is critical for structural analysis, material ordering, and shipping logistics.

How It Works

The calculator finds the weight by calculating the volume of the material in the tube and multiplying it by its density. You'll need to provide:

Outer Diameter: The full outer diameter of the tube in millimeters (mm).

Wall Thickness: The thickness of the tube's wall in millimeters (mm).

Length: The total length of the tube section in millimeters (mm).

Density: The material density in kg/m³. The default is set to 7850 for mild steel, but this can be easily changed for other materials like aluminum (~2700 kg/m³) or stainless steel (~8000 kg/m³).

The tool calculates the volume of the outer cylinder and subtracts the volume of the inner hollow space to find the material's true volume, then provides an accurate weight in kilograms (kg).
