2" x 2" x 0.12" wall copper square tube weighs 3.498 lb per ft (5.21 kg per m). Weight = cross-section area x length x 0.323 lb per cubic inch.
How much does copper square tube weigh per foot?
| Size | Area (sq in) | lb per ft | kg per m | 12 ft length, lb |
|---|---|---|---|---|
| 0.75" x 0.75" x 0.065" wall | 0.1781 | 0.690 | 1.03 | 8.3 |
| 1" x 1" x 0.065" wall | 0.2431 | 0.942 | 1.40 | 11.3 |
| 1" x 1" x 0.12" wall | 0.4224 | 1.637 | 2.44 | 19.6 |
| 1.5" x 1.5" x 0.12" wall | 0.6624 | 2.567 | 3.82 | 30.8 |
| 2" x 2" x 0.12" wall | 0.9024 | 3.498 | 5.21 | 42.0 |
| 2" x 2" x 0.25" wall | 1.7500 | 6.783 | 10.09 | 81.4 |
| 3" x 3" x 0.1875" wall | 2.1094 | 8.176 | 12.17 | 98.1 |
| 4" x 4" x 0.25" wall | 3.7500 | 14.535 | 21.63 | 174.4 |
Formula: area = outside squared minus (outside minus 2 x wall) squared; weight = area x length x 0.323 lb/in3. Corner radii are ignored, so real stock runs one to three percent lighter than the table. For any other size use the metal weight calculator.

Frequently asked questions
How do you calculate the weight of copper square tube?
Multiply the cross-section area in square inches by the length in inches and by the density, 0.323 lb per cubic inch for copper (110). For this shape the area is: area = outside squared minus (outside minus 2 x wall) squared. A foot of stock is 12 inches, so weight per foot is area x 12 x 0.323.
How does copper compare with steel by weight?
Copper is 14% heavier than carbon steel for the same size: 0.323 lb per cubic inch against 0.2836. The same bar or plate in copper weighs 1.14 times the steel figure.
