Copper Wire Weight Calculator

Find the mass of a copper wire.

Mass 2.24

Mass 2,240

Formula: mass = density · length · area (copper 8960 kg/m³)

Step-by-step with your numbers:

1. Values used:

2. Length = 100

3. Cross-section area = 2.5 mm²

5. Mass = 2.24

6. Mass = 2,240

Did we solve your problem today?

Estimate how much a length of copper wire weighs from its cross-section.

The math behind it

mass = density × volume = 8960 kg/m³ × length × area.

100 m of 2.5 mm² copper → about 2.24 kg.

Why does copper weight matter?

It affects shipping cost and the scrap value of cabling.
