Cable Weight Calculator

The Cable Weight Calculator is a useful tool for estimating the weight of a cable based on its diameter and length. Whether you’re working with electrical cables, steel wires, or any other type of cable, knowing the weight is crucial for various applications.

Formula: The cable weight is calculated using the formula: Weight (grams) = π * (Diameter / 2)^2 * Length * Density, where Density is typically 7.85 g/cm³ for steel cables.

How to Use:

  1. Enter the diameter of the cable in millimeters (mm).
  2. Enter the length of the cable in meters (m).
  3. Click the “Calculate” button.
  4. The result will display the estimated cable weight in grams.

Example: Suppose you have a steel cable with a diameter of 5 mm and a length of 100 meters. After using the Cable Weight Calculator, you will find that the cable weighs approximately 1962.50 grams.


  1. Q: What is the density value used for steel cables in the formula? A: The typical density value for steel cables is 7.85 grams per cubic centimeter (g/cm³).
  2. Q: Is this calculator suitable for all types of cables? A: This calculator works best for cables made of materials with known densities, such as steel or copper.
  3. Q: Can I use this calculator for cables with non-circular cross-sections? A: This calculator assumes a circular cross-section. For irregular shapes, results may not be accurate.
  4. Q: What are the units of measurement for diameter and length? A: Diameter is in millimeters (mm), and length is in meters (m).
  5. Q: Is this calculator applicable to lightweight cables? A: Yes, you can use this calculator for lightweight cables, but the result will be in grams.

Conclusion: The Cable Weight Calculator is a handy tool for quickly estimating the weight of cables, which can be vital for various applications like construction, engineering, and logistics. By inputting the cable’s diameter and length, you can obtain accurate weight measurements, ensuring your projects are efficient and safe.
