1.25" OD x 0.12" wall bronze round tube weighs 1.646 lb per ft (2.45 kg per m). Weight = cross-section area x length x 0.322 lb per cubic inch.
How much does bronze round tube weigh per foot?
| Size | Area (sq in) | lb per ft | kg per m | 12 ft length, lb |
|---|---|---|---|---|
| 0.5" OD x 0.065" wall | 0.0888 | 0.343 | 0.51 | 4.1 |
| 0.75" OD x 0.065" wall | 0.1399 | 0.540 | 0.80 | 6.5 |
| 1" OD x 0.065" wall | 0.1909 | 0.738 | 1.10 | 8.9 |
| 1" OD x 0.12" wall | 0.3318 | 1.282 | 1.91 | 15.4 |
| 1.25" OD x 0.12" wall | 0.4260 | 1.646 | 2.45 | 19.8 |
| 1.5" OD x 0.12" wall | 0.5202 | 2.010 | 2.99 | 24.1 |
| 2" OD x 0.12" wall | 0.7087 | 2.739 | 4.08 | 32.9 |
| 2" OD x 0.25" wall | 1.3744 | 5.311 | 7.90 | 63.7 |
| 3" OD x 0.25" wall | 2.1598 | 8.346 | 12.42 | 100.1 |
Formula: area = pi / 4 x (OD squared minus ID squared); weight = area x length x 0.322 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 bronze round tube?
Multiply the cross-section area in square inches by the length in inches and by the density, 0.322 lb per cubic inch for bronze (932 bearing bronze). For this shape the area is: area = pi / 4 x (OD squared minus ID squared). A foot of stock is 12 inches, so weight per foot is area x 12 x 0.322.
How does bronze compare with steel by weight?
Bronze is 14% heavier than carbon steel for the same size: 0.322 lb per cubic inch against 0.2836. The same bar or plate in bronze weighs 1.14 times the steel figure.
