Square Tube Weight Calculator


The Square Tube Weight Calculator is a simple tool designed to provide the weight of a square tube based on its side length. Whether you’re involved in construction, engineering, or any other field requiring precise weight calculations, this calculator can be a handy solution.

Formula: To calculate the weight of a square tube, we use the formula: Weight = Side Length^2 * 0.00785

How to Use:

  1. Enter the side length of the square tube in the provided input field.
  2. Click the “Calculate” button.
  3. The calculated weight of the square tube will be displayed.

Example: Suppose you have a square tube with a side length of 5 units. After entering 5 in the input field and clicking “Calculate,” the tool will show the weight of the tube as 0.19625 kg.


  1. Q: Can I use this calculator for tubes with different units of measurement? A: Yes, as long as you enter the side length in consistent units, the calculator will provide accurate results.
  2. Q: What is the significance of the constant 0.00785 in the formula? A: The constant 0.00785 represents the density of steel, and it is used to convert the calculated volume to weight.
  3. Q: Is the calculator suitable for other materials besides steel? A: This calculator is specifically designed for steel square tubes. Different materials have different densities, so the formula would need adjustment for accuracy.
  4. Q: Can I use decimal values for the side length? A: Yes, the calculator accepts decimal values for precise measurements.
  5. Q: How accurate is the calculated weight? A: The calculator provides a reasonably accurate estimate, but for critical applications, it is advisable to consult detailed engineering specifications.

Conclusion: The Square Tube Weight Calculator simplifies the process of determining the weight of square tubes, making it a valuable tool for professionals in various industries. Use this calculator for quick and reliable weight calculations, ensuring precision in your projects.
