Wire Weight Calculator
Estimate the total weight of a wire or cable from its material, diameter, length, and number of conductors.
Enter wire details
Result
Enter the wire dimensions to estimate its weight.
Diameter controls area
Wire weight rises with the square of diameter because cross-sectional area is based on the wire radius.
Material density matters
Copper is much denser than aluminium, so equal-size copper wire weighs considerably more.
Count every conductor
For multi-core cable, multiply the single-conductor volume by the total number of conductors.
Frequently asked questions
How is wire weight calculated?
The calculator finds the circular cross-sectional area, multiplies it by length and conductor count to get volume, then multiplies volume by material density.
Does this include insulation?
No. The result estimates the metallic conductor only. Finished cable weight is usually higher because of insulation, shielding, filler, armour, and jackets.
Can I calculate stranded wire?
Yes, when the entered diameter represents the equivalent total metallic cross-sectional diameter. For precise stranded-wire calculations, use the sum of all strand areas.
Which density is used for copper?
This calculator uses approximately 8,960 kg/m³ for copper. Real alloys and manufacturing specifications may differ slightly.
