Copper Weight Calculator

Bar, tube, sheet and busbar weight for ETP, OFHC and cupronickel grades

Copper is the heaviest metal most workshops handle daily — pure grades weigh about 8,940 kg/m³, 14% more than steel. With copper also being one of the most expensive base metals, weight accuracy directly drives cost: busbars, earthing strips, and tubes are all bought and sold per kilogram.

The calculator covers electrolytic (ETP C11000, 8,930 kg/m³) and oxygen-free (OFE/OFHC, 8,940 kg/m³) copper for electrical work, plus beryllium copper and cupronickel alloys for springs, molds, and marine service.

A practical example: a standard 40×10 mm copper busbar weighs 3.57 kg per meter. At current copper prices, a 10-meter run is a purchase you want to calculate before ordering, not after.

Frequently Asked Questions

How much does a copper busbar weigh?

Copper busbar weight per meter = width (m) × thickness (m) × 8,930 kg/m³. A 40×10 mm busbar weighs about 3.57 kg/m; a 100×10 mm busbar weighs about 8.93 kg/m.

Is copper heavier than steel?

Yes — copper weighs about 8,940 kg/m³, roughly 14% more than steel (7,850 kg/m³) and over three times more than aluminum (2,700 kg/m³).

What does copper sheet weigh per m²?

Copper sheet weighs about 8.93 kg per square meter per millimeter of thickness. A 2000×1000×1 mm sheet is roughly 17.9 kg.
