1.25" OD x 0.12" wall stainless steel round tube weighs 1.477 lb per ft (2.20 kg per m). Weight = cross-section area x length x 0.289 lb per cubic inch.
How much does stainless steel 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 | 0.308 | 0.46 | 3.7 |
| 0.75" OD x 0.065" wall | 0.1399 | 0.485 | 0.72 | 5.8 |
| 1" OD x 0.065" wall | 0.1909 | 0.662 | 0.99 | 7.9 |
| 1" OD x 0.12" wall | 0.3318 | 1.151 | 1.71 | 13.8 |
| 1.25" OD x 0.12" wall | 0.4260 | 1.477 | 2.20 | 17.7 |
| 1.5" OD x 0.12" wall | 0.5202 | 1.804 | 2.68 | 21.7 |
| 2" OD x 0.12" wall | 0.7087 | 2.458 | 3.66 | 29.5 |
| 2" OD x 0.25" wall | 1.3744 | 4.767 | 7.09 | 57.2 |
| 3" OD x 0.25" wall | 2.1598 | 7.490 | 11.15 | 89.9 |
Formula: area = pi / 4 x (OD squared minus ID squared); weight = area x length x 0.289 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 stainless steel round tube?
Multiply the cross-section area in square inches by the length in inches and by the density, 0.289 lb per cubic inch for stainless steel (304). 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 0.289.
How does stainless steel compare with steel by weight?
Stainless steel is 2% heavier than carbon steel for the same size: 0.289 lb per cubic inch against 0.2836. The same bar or plate in stainless steel weighs 1.02 times the steel figure.
