The Copper Wire Weight Calculator is a practical online tool designed for engineers, electricians, fabricators, and metal traders to estimate the weight of copper or any metallic wire quickly. By entering just the diameter, length, and material density, users can instantly find out the total weight, volume, and cross-sectional area of the wire.
This calculator helps in accurate material estimation, project costing, and waste reduction, essential for construction, electrical wiring, and manufacturing applications. The formula used is based on the geometric volume of a cylindrical wire and the known density of copper (8900 kg/m³).
Built with precision and ease of use, this tool adheres to engineering standards and is suitable for both professional and academic use. It enhances accuracy, efficiency, and ensures you get reliable results in seconds.
How to Use the Copper Wire Weight Calculator
- Enter the wire diameter in millimetres (mm).
- Input the total wire length in meters (m).
- Check or edit the material density (default: 8900 kg/m³ for copper).
- Click “Calculate” to get:
- Estimated weight (kg)
- Cross-sectional area (m²)
- Wire volume (m³)
- Use “Clear” to reset the fields or “Copy Summary” to copy your results.
- For documentation or records, you can export the result as a CSV file.
Formula Used
The calculator uses the standard cylindrical volume formula combined with material density to determine the wire weight.
Weight (kg) = Volume × Density
where,
Volume = π × r² × L
Substituting r = d / 2, we get:
Weight (kg) = π × (d / 2)² × L × Density
Variables:
- d = Wire Diameter (m)
- L = Wire Length (m)
- Density = Material Density (kg/m³)
Example Calculation
Let’s calculate the weight of a copper wire with the following data:
- Diameter = 10 mm (0.01 m)
- Length = 50 m
- Density = 8900 kg/m³
Step 1:
Radius = 0.01 m ÷ 2 = 0.005 m
Step 2:
Volume = π × (0.005)² × 50 = 0.00393 m³
Step 3:
Weight = 0.00393 × 8900 = 35.04 kg
Final Weight = 35.04 kg
This copper wire weight calculator simplifies technical computations for engineers, electricians, and metal suppliers. It ensures fast, precise, and reliable weight estimation, helping you save time, reduce material wastage, and plan projects efficiently.
By using this tool, you can calculate wire weights for copper, aluminium, or any metal just by changing the density value, making it a versatile choice for industrial and educational use.
