2" x 2" x 0.12" wall brass square tube weighs 3.324 lb per ft (4.95 kg per m). Weight = cross-section area x length x 0.307 lb per cubic inch.
How much does brass 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 | 0.656 | 0.98 | 7.9 |
| 1" x 1" x 0.065" wall | 0.2431 | 0.896 | 1.33 | 10.7 |
| 1" x 1" x 0.12" wall | 0.4224 | 1.556 | 2.32 | 18.7 |
| 1.5" x 1.5" x 0.12" wall | 0.6624 | 2.440 | 3.63 | 29.3 |
| 2" x 2" x 0.12" wall | 0.9024 | 3.324 | 4.95 | 39.9 |
| 2" x 2" x 0.25" wall | 1.7500 | 6.447 | 9.59 | 77.4 |
| 3" x 3" x 0.1875" wall | 2.1094 | 7.771 | 11.56 | 93.3 |
| 4" x 4" x 0.25" wall | 3.7500 | 13.815 | 20.56 | 165.8 |
Formula: area = outside squared minus (outside minus 2 x wall) squared; weight = area x length x 0.307 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 brass square tube?
Multiply the cross-section area in square inches by the length in inches and by the density, 0.307 lb per cubic inch for brass (360). 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 0.307.
How does brass compare with steel by weight?
Brass is 8% heavier than carbon steel for the same size: 0.307 lb per cubic inch against 0.2836. The same bar or plate in brass weighs 1.08 times the steel figure.
