Copper Wire Weight Calculator
kg per km of copper conductor from cross-section — cable estimating basic.
8.96 kg/km per mm² — copper theft economics and cable tenders both run on this constant. Aluminium conductor: 2.7 (but needs 1.6× the section for equal conductance).
Formula
Copper Wire Weight Calculator is a free copper wire weight for design engineers, metallurgists and QA inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Copper Wire Weight Calculator
kg per km of copper conductor from cross-section — cable estimating basic. The calculation implements kg/km = mm² × 8.96 (IEC 60228 conductor masses). 8.96 kg/km per mm² — copper theft economics and cable tenders both run on this constant. Aluminium conductor: 2.7 (but needs 1.6× the section for equal conductance).

Frequently asked questions
What formula does the Copper Wire Weight Calculator use?+
It computes kg/km = mm² × 8.96, per IEC 60228 conductor masses. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
8.96 kg/km per mm² — copper theft economics and cable tenders both run on this constant. Aluminium conductor: 2.7 (but needs 1.6× the section for equal conductance).
Where do the material property defaults come from?+
Defaults are standard handbook values (ASM, manufacturer datasheets, the cited standard). Always substitute certified values from your material's test certificate for critical work.
Is the Copper Wire Weight Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
